pSemi’s PE42524 is a HaRP™ technology-enhanced reflective SPDT RF switch die that supports a wide frequency range from 10 MHz to 40 GHz. This wideband flip-chip switch delivers high isolation performance, excellent linearity, and low insertion loss, making this device ideal for test and measurement (T&M), microwave backhaul, radar, and military communications (mil-comm) applications. At 30 GHz, the PE42524 exhibits 17 dB active port return loss, 47 dB isolation and 2.2 dB insertion loss. No blocking capacitors are required if DC voltage is not present on the RF ports. The PE42524 is manufactured on Peregrine's UltraCMOS process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate.
