Disintermediation means the elimination of the middleman or middleprocess as made possible by the continuously evolving technology, including automation, the Internet, computing, etc. Among the physical functions that continue to be disintermediated are those of wholesalers, retailers, distributors, bank tellers, insurance brokers, travel agents, and gas station attendants. Indeed, even professionals such as engineers, technicians, doctors, and scientists face disintermediation. As long as it's not one's own livelihood that is affected by disintermediation, one is likely to embrace these developments. People who benefit from disintermediation are the ones who can develop a product or service that disintermediates something or someone else, make money, and then get out before suffering disintermediation themselves. There is no end to the human functions that can be disintermediated, and today's world is rapidly becoming one in which many people are busy working on unemploying others by replacing their job with technology. © 2010 IEEE.

A novel PLL frequency synthesizer architecture is presented. The proposed architecture offers improved phase noise characteristics by removing frequency division from the PLL feedback path. This minimizes the impact of the phase detector residual noise floor. Moreover, phase noise can be further improved by inserting a frequency multiplier into the feedback path. A 5 MHz to 26.5 GHz synthesizer module based on the proposed architecture has been developed. Phase noise at 26.5 GHz output and 10 kHz offset is measured at -110 dBc/Hz. The measured spurs do not exceed -60 dB level. The switching time is less than 100 microseconds for any frequency step within the entire operating range. © 2011 Engineers Australia.

Phase Matrix has introduced the QuickSyn™ series of microwave frequency synthesizers. The employed patented architecture provides a unique combination of fast-switching speed and low phase noise characteristics. The main idea is to substitute a slow-tuning, bulky and expensive YIG oscillator (normally used in high-end designs) with a tiny VCO that can easily support microsecond tuning. The QuickSyn synthesizer is available in two models, the FSW-0010 and FSW-0020, covering 0.1 to 106Hz and 0.2 to 20 6Hz, respectively. Both models utilize broadband solid-state VCOs that offer fundamental output to 10 and 20 GHz, respectively. The synthesizer includes a highly stable internal OCXO that is factory calibrated to a GPS standard to ensure adequate accuracy of the synthesized signal. VCO phase noise is controlled by utilizing an ultra low-noise reference OCXO as well as a very wide (a few MHz) loop bandwidth.

Dr. Alexander Chenakin shares his views on the anatomy of the fractional-N synthesis and discusses some new ways to address the limitations of the existing technology. There are many techniques to reduce fractional-N spurs, which can be accomplished by adding or subtracting a voltage at the phase detector output during the frequency division change. Another method is based on using a multi-modulus divider that allows a larger number of division coefficients. The mixer inputs are generated internally within the same PLL, eliminating the need for separate offset frequency source. Two frequency dividers divide the VCO output frequency to generate the required mixer inputs.

Some of the latest technological innovations in Russia in the field of RF/microwave signal generation are discussed. Morion has recently developed a new family of low phase noise OCXOs (MV317 and MV318) offering a noise floor down to 178 dBc/Hz and excellent aging characteristics. These parameters are achieved using in-house proprietary technologies for the design and production of precision blanks in combination with advanced filtering methods incorporated into the OCXO design. Magic Xtal develops and manufactures OCXOs utilizing the unique internally heated resonator (IHR) technology. The IHR design incorporates the whole oven-controlled system integrated with the crystal plate inside a miniature TO-8 vacuum holder. Spectran has developed a low-cost 20 GHz synthesizer module. This is a phase-lock-loop (PLL) design that integrates a DDS for fine frequency resolution. The module provides 9 kHz to 20 GHz frequency coverage with fast switching speed and a resolution of 0.01 Hz.
