Skyworks Solutions, Inc. is a semiconductor company headquartered in Woburn, Massachusetts.The company manufactures semiconductors for use in radio frequency and mobile communications systems. Its products include power amplifiers, front end modules and RF products for handsets and wireless infrastructure equipment. The Company's portfolio includes amplifiers, attenuators, circulators, demodulators, detectors, diodes, directional couplers, front-end modules, hybrids, infrastructure RF subsystems, isolators, lighting and display solutions, mixers, modulators, optocouplers, optoisolators, phase shifters, PLLs/synthesizers/VCOs, power dividers/combiners, power management devices, receivers, switches and technical ceramics.During 2009 and 2010, Skyworks benefitted from industry moves towards higher-end mobile phones with multi-band communication, exiting fiscal year 2010 with revenue of $1,072 million. Although operating in a market dominated by big name companies, it doubled its share price in one year, and in March 2010 was tipped by the Forbes-owned Investopedia website as one of three "not-so-famous" stocks likely to give good capital returns in 2010.The company formed as a result of a merger of Alpha Industries and the wireless communications division of Conexant, which took effect on 26 June 2002. Headquartered in Woburn, Massachusetts, Skyworks has manufacturing facilities in Woburn, Newbury Park, California and Mexicali, Mexico and design centers in Irvine, California, Santa Rosa, California, Newbury Park, Woburn, Greensboro, North Carolina and Cedar Rapids, Iowa. The music video for The Postal Service's song "Such Great Heights" is set in the Newbury Park chip fabrication plant. According to its website, the company has design, engineering, manufacturing, marketing, sales and service facilities throughout North America, Europe, Japan and Asia.A Skyworks 2614B 315BB seem to be used in some hardware revisions of the PlayStation 4.

Doherty power amplifier combiner with tunable impedance termination circuit. A signal combiner can include a balun transformer circuit having a first coil and a second coil. The first coil can be implemented between a first port and a second port. The second coil can be implemented between a third port and a fourth port. The first port and the third port can be coupled by a first capacitor. The second port and fourth port can be coupled by a second capacitor. The first port can be configured to receive a first signal. The fourth port can be configured to receive a second signal. The second port can be configured to yield a combination of the first signal and the second signal. The signal combiner can include a termination circuit that couples the third port to a ground. The termination circuit can include a tunable impedance circuit.

A radio frequency (RF) module comprises an electrical reference, or ground, plane to which one or more RF devices disposed on the module are electrically coupled, and may be disposed beneath the RF devices. The reference plane may be segmented as to form one or more segments of the reference plane that are at least partially electrically isolated from surrounding segments or devices. A module may have a plurality of devices disposed thereon, wherein separate, at least partially isolated reference planes, correspond to different devices of the module. The reference plane may be etched or cut to achieve such segmentation.

Apparatus and methods for wideband envelope tracking systems are disclosed herein. In certain implementations, an envelope tracker includes a DC-to-DC converter, a current digital-to-analog converter (DAC), an error amplifier, a feedback circuit, and an AC combiner. The current DAC receives a digital envelope signal, and uses the digital envelope signal to generate an envelope current. The feedback circuit is connected between an output and an inverting input of the error amplifier, and the envelope current is provided to the error amplifiers inverting input. Additionally, the AC combiner generates a power amplifier supply voltage by combining an output of the DC-to-DC converter and an output of the error amplifier.


Circuits and methods related to radio-frequency (RF) receivers having carrier aggregation. In some embodiments, a carrier aggregation (CA) circuit can include a first filter configured to allow operation in a first frequency band, and a second filter configured to allow operation in a second frequency band. The CA circuit can further include a first path implemented between the first filter and a common node, with the first path being configured to provide a substantially matched impedance for the first frequency band and a substantially open-circuit impedance for the second frequency band. The CA circuit can further include a second path implemented between the second filter and the common node, with the second path being configured to provide a substantially matched impedance for the second frequency band and a substantially open-circuit impedance for the first frequency band.


Architectures and methods related to improved isolation for diplexer paths. In some embodiments, an architecture for routing radio-frequency (RF) signals can include an input node and an output node, and a distributed network of signal paths implemented between the input node and the output node. The distributed network of signal paths can include a first path having N switches including a selected switch, with the quantity N being an integer greater than 2. The first path can be capable of routing a first RF signal between the input node and the output node when enabled. The distributed network of signal paths can further include a second path capable of routing a second RF signal between the input node and the output node, with the second path including the selected switch. The second path can include a plurality of open switches when disabled and the first path is enabled.
