Switch targets automotive wireless over 50 to 3000 MHz

December 19, 2014 // By Jean-Pierre Joosting
Richardson RFPD has announced the availability and full design support capabilities for an RF single-pole four-throw switch from Peregrine Semiconductor Corporation.

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 at 1000 MHz, and IIP3 of +68 dBm. Blocking capacitors are not required if DC voltage is not present on the RF ports.

The 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.

Key features of the PE423641 include operating temperatures up to +105ºC; low harmonics of 2fo = -83 dBc and 3fo = -77 dBc at +35 dBm; and IMD3 of -111 dBm at WCDMA band 1.

The switch boasts high EDS performance of 2-kV HBM on all pins, 100-V MM on all pins, and 1-kV CDM on all pins. An integrated decoder enables 2-pin control.
