pSemi introduces RF switch with 52 dBm PMAX,PEAK and 90-dBm IIP3 linearity

pSemi Corporation announced the introduction of a new high-performance mmWave SPDT RF switch: the PE42528. Built on pSemi’s newly announced UltraCMOS+ platform, this innovative packaged solution provides broadband frequency coverage spanning from near DC to 30 GHz and offers optimized performance and cost effectiveness across a broad spectrum of applications.

With pSemi’s proprietary UltraCMOS+ technology at its core, the PE42528 delivers low insertion loss, rapid switching time, high power handling, and exceptional isolation performance. These features make it perfect for applications including test and measurement (T&M), 5G mmWave, microwave backhaul, radar, satellite communications, and more. Additionally, the PE42528 operates efficiently in extreme environments, with a temperature range of -40 °C to 105 °C, and is housed in a compact 20-lead 3 × 3 mm LGA package.

pSemi will showcase PE42528 at the 2025 International Microwave Symposium (IMS), to be held June 15–20, 2025, in San Francisco. To see a live demonstration, please stop by booth #443. PE42528 samples are available now, with commercial availability in early 2026. For more information, please visit the PE42528 product page.
