SPDT RF switches for wireless infrastructure, ISM, broadband apps

Peregrine Semiconductor has introduced the PE4250 and PE4251, a new series of SPDT RF switches that are suitable for wireless infrastructure, 2.4GHz ISM, and broadband applications for fiber optics and Multichannel Multipoint Distribution Service (MMDS).

The PE4250 and PE4251 utilize Peregrine's HaRP technology that eliminates gate and phase lag and results in fast settling time and no insertion loss drift. In addition, the devices have low Insertion Loss (IL) of 0.55 to 0.75 dB typical from 10MHz to 3GHz, high Isolation across the operating range (51-40 dB for PE4250 and 62-43 dB for PE4251), and high ESD protection of 4000 V HBM.

The PE4250 reflective and PE4251 absorptive 50-Ohm SPDT RF switches deliver high linearity and are pin- and logic-compatible, and alternatives to gallium-arsenide (GaAs)-based ICs. These HaRP-enhanced devices operate near DC through 3 GHz and deliver RF performance with P1dB of +30.5 dBm and IP3 (typ) of +59 dBm, and fast switching speed of 150 nS.

The new switches feature single-pin or complementary control inputs and no blocking capacitors are required.
