RF single-pole switch covers 50 to 3000MHz
Richardson RFPD has availability and full design support capabilities for a new RF single-pole four-throw switch from Peregrine Semiconductor. The PE423641 is HaRP technology-enhanced and has received AEC-Q100 Grade 2 certification by meeting the quality and performance standards required for use in harsh automotive environments.
It features insertion loss of 0.5 dB and isolation of 32 dB @ 1000 MHz, and IIP3 of +68 dBm. Blocking capacitors are not required if DC voltage is not present on the RF ports.
The new SP4T switch is designed to cover a wide range of automotive wireless applications from 50 to 3000 MHz, including cellular antenna band switching, automotive infotainment, and traffic safety applications.
It is manufactured on Peregrine’s UltraCMOS process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering excellent RF performance.
According to Peregrine, additional key features of the device include: support for operating temperatures up to +105ºC; low harmonics of 2fo = -83 dBc and 3fo = -77 dBc @ +35 dBm; IMD3 of -111 dBm @ WCDMA band 1; and itegrated decoder for 2-pin control that accepts 1.8V and 2.75V levels
