Richardson RFPD Inc. announces immediate availability and full design support capabilities for two new RF single-pole, double-throw (SPDT) switches from Peregrine Semiconductor Corp. (Peregrine).

Designed for LTE and 3G small cells, other wireless infrastructure systems, and land mobile radios targeting LMR to LTE conversion, thenew switches deliver 30W power handling and excellent linearity across the UHF/VHF through LTE frequency bands, thereby reducing board area, power consumption and design-in complexity compared to traditional, discrete solutions.

The PE42820operates from 30 to 2700 MHz and is a pin-compatible upgraded version of the PE42510A, with a wider frequency and power supply range, and external negative supply option. The PE42821 is a pin-compatible faster switching version of the PE42820 and operates from 100 to 2700 MHz. Both devices feature low insertion loss and high power handling and are offered in 32-lead 5x5 mm QFN packages. No external blocking capacitors are required if 0V DC is present on the RF ports.

The new switches are manufactured on Peregrine's UltraCMOS process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS. Peregrine’s HaRP technology enhancements provide for new RF architectures and unmatched linearity in RF front end solutions.
