Peregrine PE42820 and PE42821 SPDT RF switches

Peregrine Semiconductor Corporation has released its two latest RF single-pole-double-throw (SPDT) switches. They are designed for LTE and 3G small cells, other wireless infrastructure systems and land mobile radios targeting LMR to LTE conversion.

The switches deliver 30 W power handling and good linearity across the UHF/VHF through LTE frequency bands. They are therefore said to reduce board area, power consumption and design-in complexity compared to traditional, discrete solutions.

The PE42820 operates 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 5 x 5 mm QFN packages. No external blocking capacitors are required if 0 VDC is present on the RF ports. The switches are manufactured on Peregrine’s UltraCMOS process, a variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS.
