GaN has been able to outperform GaAs PAs and challenge LDMOS PAs, but it has had only limited success in some high performance markets due to most cost associated with it. This is changing as GaN on Si is ready to scale to 8 inch wafers and use low cost plastic packaging techniques that will significantly reduce the cost of GaN on Si and allow it to become a mainstream solution in the RF industry. CMOS technology also continues to rapidly dominate any market where it meets the required performance. This is due to the amount of investment in CMOS technology has led to massive manufacturing scale and continuous process technology improvements. CMOS represents an inflection point for rapid transition from an incumbent technology to CMOS when it reaches the equivalent performance. The integrated RFFE solution based on the UItraCMOS 10 technology platform offers an architecture that is 100 percent CMOS-based, which enables all components to be integrated including 3-path, multimode, multiband PA and antenna switch.

We caution the reader to carefully consider such factors. MACOM undertakes no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise. Discussion Regarding the Use of Historical Non-GAAP Financial Measures In addition to United States Generally Accepted Accounting Principles (“GAAP”) reporting, MACOM provides investors with financial measures that have not been calculated in accordance with GAAP, such as Pro Forma Adjusted EBITDA, Adjusted Income from Operations and Pro Forma credit agreement EBITDA. This non-GAAP information, as calculated pursuant to our credit agreement, excludes the effect, where applicable, of discontinued operations, intangible amortization expense, share-based compensation costs, impairment and restructuring charges, changes in common stock warrant liability, financing and litigation costs, acquisition and integration related costs, other costs and the tax effect of each adjustment. This non-GAAP information, as calculated pursuant to our credit agreement, includes consulting agreement related income associated with the Automotive divestiture. Management believes that these excluded items are not reflective of our underlying performance. Management uses Pro Forma Adjusted EBITDA, Adjusted Income from Operations and Pro Forma credit agreement EBITDA to: evaluate our ongoing operating performance and compare it against prior periods, make operating decisions, forecast future periods, evaluate potential acquisitions, compare our operating performance against peer companies and assess certain compensation programs. The exclusion of these and other similar items from our non-GAAP financial results should not be interpreted as implying that these items are non-recurring, infrequent or unusual. We believe this non-GAAP financial information provides additional insight into our ongoing performance and have therefore chosen to provide this information to investors for a more consistent basis of comparison and to help them evaluate the results of our ongoing operations and enable more meaningful period-to-period comparisons. This non-GAAP financial information is provided in addition to, and not as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. A reconciliation between GAAP and non-GAAP financial data is included in the supplemental financial data attached to this press release. Investors are cautioned against placing undue reliance on non-GAAP financial measures and are urged to review and consider carefully the adjustments made by management to the most directly comparable GAAP financial measures to arrive at non-GAAP financial measures. Non-GAAP financial measures may have limited value as analytical tools because they may exclude certain expenses that some investors consider important in evaluating our operating performance or ongoing business performance. Further, non-GAAP financial measures may have limited value for purposes of drawing comparisons between companies because different companies may calculate similarly titled non-GAAP financial measures in different ways because non-GAAP measures are not based on any comprehensive set of accounting rules or principles. Additional information and management’s assessment regarding why certain items are excluded from our Non-GAAP financial measures are summarized below: Amortization Expense - is related to acquired intangible assets which are based upon valuation methodologies, and are generally amortized over the expected life of the intangible asset at the time of acquisition, which may result in amortization amounts that vary over time. The expense is not considered by management in making operating decisions, and the expense is non-cash. Share-Based and Non-cash Compensation Expense - includes share based compensation including awards that are equity and liability classified on our balance sheet as well as non-cash compensation expense primarily associated with amounts due to employees of an acquired business that were placed in escrow at the time of the acquisition and amortized as expense over a 2-year period. Share Based Compensation expense is partially outside of our control due to factors such as stock price volatility and interest rates, which may be unrelated to our operating performance during the period in which the expense is incurred. It is an expense based upon valuation methodologies and assumptions that vary over time, and the amount of the expense can vary significantly between companies due to factors that can be outside of their control. Share-based and Non-Cash Compensation Expense amounts are not considered by management in making operating decisions. Impairment Charges - includes expenses associated with our strategic decision to exit a product line and end programs with a license and technology transfer as well as certain related fixed assets and inventory. We believe these charges are one-time in nature and are not correlated to future business operations and including such charges does not reflect our ongoing operations. Restructuring Charges - includes amounts primarily associated with approved plans to reduce staffing and manufacturing or administrative footprints. We believe these amounts are not correlated to future business operations and including such charges does not reflect our ongoing operations. Litigation Costs - includes gains, losses and expenses related to the resolution of other-than-ordinary-course threatened and actually filed lawsuits and other-than-ordinary-course contractual disputes and legal matters. We exclude these gains and losses because they are not considered by management in making operating decisions. We believe such gains, losses and expenses do not necessarily reflect the performance of our ongoing operations for the period in which such charges are recognized and the amount of such gains or losses and expenses can vary significantly between companies and make comparisons less reliable. Acquisition and Integration Related Costs - includes such items as professional fees incurred in connection with pre-acquisition and integration specific activities, post-acquisition employee retention amounts, contingent consideration adjustments, severance and other amounts accrued or paid to terminated employees of acquired businesses, costs including salaries incurred which are not expected to have a continuing contribution to operations or are expected to have a diminishing contribution during the integration period and the amortization of the fair market step-up value of acquired inventory and fixed assets. We believe the exclusion of these items is useful in providing management a basis to evaluate ongoing operating activities and strategic decision making. Discontinued Operations excluding consulting income - includes the profit and loss amounts of discontinued operations, with the exception of consulting income associated with a consulting agreement we entered into at the time of our Automotive business divestiture. We believe excluding gains and losses associated with historically divested businesses from our net income provides management with a comparable basis to our current ongoing operating activities. We do not exclude the consulting agreement income classified as discontinued operations because management views this income as part of our ongoing operations and correlated with future operations. Other - historical amounts primarily include transaction expenses incurred as part of our Credit Agreement Amendment in the fourth fiscal quarter of 2016. We believe these amounts are not correlated to future business operations and including such charges does not reflect our ongoing operations. Adjusted EBITDA - is a calculation that adds depreciation expense and consulting agreement income to our Adjusted Non-GAAP Income from Operations. Adjusted EBITDA is a measure that management reviews and utilizes for operational analysis purposes. We believe competitors and others in the financial industry utilize this Non-GAAP measure for analysis purposes. Credit Agreement Adjustments - are amounts which under our credit agreement we are required and or permitted to adjust in arriving at our consolidated trailing twelve months EBITDA including certain share-based compensation amounts and certain estimated run rate savings and synergies associated with acquisitions.

This paper presents the performance of a first pass design W-band low noise amplifier MMIC, based on coplanar waveguide (CPW) technology, and utilising 100-nm gate-length GaAs pseudomorphic power HEMTs. With a chip size of less than 1.4 mm2, this two-stage LNA achieves an average small signal gain of 12 dB between 80 and 100 GHz. The measured noise figure averages 5 dB up to 94 GHz. To the author knowledge, this performance is one of the very few reported for W-band LNAs fabricated in commercially available foundry process. It is also comparable to the best results reported with more advanced InP or Metamorphic HEMT low noise technologies. © 2014 IEEE.

This paper presents the influence of a doped Si region during the epi growth process on the performance of GaN on Si Power Amplifiers with significant improvement in GaN on Si performance achieved by reducing the doped Si region. Through load-pull and waveform measurements of a PCM GaN on Si device the impact of the doped region below the AlGaN buffer, termed the parasitic conduction layer, on PA performance is shown. By extracting a resistance value for the parasitic conduction layer a relationship between the achievable efficiency and parasitic conduction layer is developed and through further processing of the GaN on Si wafers to remove the doped Si layer this relationship proven. Enhancements in epi growth techniques to reduce the parasitic conduction layer are shown to improve the efficiency performance of the GaN on Si PA by over 7% on a 2mm device. The efficiency of a packaged 55W GaN on Si transistor also improved by over 5% from previous GaN on Si technology. © 2014 European Microwave Association-EUMA.

This paper outlines the approach used for the design of a high efficiency 30W Doherty power amplifier. The benefits of exploiting the inherent device nonlinearities for Class-J PA operation are discussed, specifically in the case of Doherty amplifiers. The combination of Class-J modes and internal device matching ensures high performance in a compact, cost-sensitive Doherty amplifier design. To validate the discussed theory, a simple 2.7 GHz symmetric Doherty PA was designed and fabricated, producing 30W of output power with greater than 60% efficiency at 6 dB back-off. The PA was subsequently linearized using a wideband 20 MHz LTE signal with a PAPR of 6.5 dB. For an ACPR of <-50 dBc, 8W of average output power was obtained with a corresponding efficiency of 60%. © 2015 EuMA.

GaN technology development has been driven primarily by government funding and R&D. GaN on silicon carbide (SiC) is being successfully applied in the military domain for applications including broadband electronic warfare jammers and radar systems, while GaN on silicon has been successfully deployed in military communications. This activity has helped GaN's penetration into commercial markets including CATV cellular infrastructure, and other applications. GaN will remain segmented into two distinct varieties to accommodate the unique price/performance requirements of these diverse commercial applications. These two varieties include CaN on SiC for specialized high performance applications and GaN on Si for cost-sensitive volume applications. GaN technology is reaching its potential, solving both the technical and cost challenges is critical to its mainstream commercial adoption.

Microwave Journal | Year: 2013

The recent emergence of GaN-based power amplifiers is equipping radar system designers to achieve high-power operation using smaller power transistors while improving efficiency, frequency bandwidth and reliability. The higher breakdown voltage performance of GaN semiconductor technology allows scaling to a higher operational voltage, which minimizes power loss, reduces power supply demand, allows for wideband impedance matching, enables system designers to use smaller energy storage capacitors and reduces current handling within the power supply system. GaN in plastic-based power transistors are also extremely lightweight compared to ceramic-packaged GaN-based offerings. Combined with significant size reduction in the external application solution and aggregated across the hundreds of power amplifiers within a typical modem military radar system, this can reduce overall system weight considerably. The GaN in plastic approach also allows for ultra-small, fully matched, integrated module solutions.
