pSemi® Corporation, a Murata company leading in the design and development of semiconductor integration and advanced connectivity, has announced the introduction of PE42448: a high-linearity SP4T RF switch manufactured on pSemi’s UltraCMOS+ advanced silicon-on-insulator (SOI) technology.
The PE42448 switch, covering 10 MHz to 6 GHz with 52 dBm PMAX, PEAK, expands pSemi’s deep RF switch portfolio by nearly breaking the 90-dBm IIP3 barrier. Historically, the level of linearity achieved by the PE42448—the world's highest for an RF SOI switch—has only been attainable through bulky, less reliable, and more costly solutions.
The SP4T is one of several first-generation switches to use pSemi’s newly announced UltraCMOS+ RF platform, providing a monolithic and simple solution to complex switch architectures and system lineups. This device also offers seamless integration with pin-for-pin compatibility with the recently announced PE42443 and PE42444.
The PE42448 also offers ease-of-use features through one logic control for two pairs of PE42448s and a simple power-up and power-down sequence. These features make this device ideal for massive multiple-input, multiple-output (MIMO), test and measurement (T&M), land mobile radio (LMR), and general-purpose applications.
“We are proud to expand our industry-leading, high-linearity, high-power RF switch offerings with the introduction of the PE42448,” says Rodd Novak, vice president of sales and marketing, pSemi. “The linearity of this switch empowers our alpha customers to drastically reduce total solution size, accelerate design cycles, and significantly reduce BOM cost and component count. I look forward to seeing how the PE42448 will be used to change system architectures in the various industry applications we support.”
By delivering superior linearity, low insertion loss, and power handling capabilities in a cost-effective, reliable, and compact form factor, the PE42448 is set to change RF system architectures, enabling a new generation of efficient designs for high-performance wireless solutions.
pSemi is showcasing the PE42448 at the 2025 International Microwave Symposium (IMS), being held from June 17–19, 2025, in San Francisco. Visit booth #443 to see a live demonstration.
