From RF-SOI pioneer Peregrine Semi comes a steady stream of new chips and design wins.
- Two UltraCMOS® MPAC–Doherty products—the PE46130 and PE46140 (press release here). These monolithic phase and amplitude controllers (MPAC) join the PE46120 in offering maximum phase-tuning flexibility for Doherty power amplifier (PA) optimization. Designed for the LTE and LTE-A wireless-infrastructure transceiver market, the MPAC–Doherty product family now extends from 1.8 to 3.8 GHz with three separate, pin-compatible parts.
- Design wins: Psemi’s high-linearity RF switches are designed into multiple DOCSIS 3.1 certified cable modems (press release here). CableLabs, the research and development consortium that develops the DOCSIS specification, has certified the first DOCSIS 3.1 cable modems. Of the certified modems, Peregrine Semiconductor’s RF switches—the UltraCMOS® PE42722 and PE42723—are designed into the cable modems that feature a band-select feature. The PE42722 and PE42723 are the only RF switches that enable dual upstream/downstream bands to reside in the same consumer premise equipment (CPE) device.
Psemi was honored with a 2015 Electronic Products “Product of the Year” award for its UltraCMOS® PE42020 True DC RF switch, the industry’s first and only RF integrated switch to operate from DC (0 Hz) to 8 GHz. (Press release here.)
- Psemi RF engineer Tero Ranta recently wrote a chapter summarizing the technical details behind how you use SOI CMOS for impedance tuning for the book “Tunable RF Components and Circuits—Applications in Mobile Handsets.” In an interview for Psemi’s SOI University, he said, “…the main point is that you can improve the performance of mobile devices by using tuning. And you can do it by using SOI technology, which is what we use at Peregrine.” He adds, “… there are many other places in the 4G and 5G smartphone RF front-ends that will require tuning going forward to optimize system performance.”
