Peregrine Enables New Approach to RF Switching in High-Power Wireless Systems
Peregrine Semiconductor Corporation  (San Diego, CA) [NASDAQ: PSMI ] has announced the PE42820 and PE42821 single-pole double throw (SPDT) switches for high-power wireless applications. The new switches provide an unprecedented combination of high-power handling and excellent linearity, while offering an integrated approach that reduces board area, power consumption, and design-in complexity compared to traditional discrete solutions. This combination makes the PE42820/821 ideal for transmit/receive, filter bank, and antenna band switching applications in high-power RF systems such as wireless infrastructure devices and land mobile radios for public safety and military environments. Features include:
- High linearity of 82 dBm IIP3 @ 850 MHz (PE42820) and 76 dBm IIP3 @ 2.7 GHz (PE42821).
- A low insertion loss of 0.35 from 30 MHz to 1 GHz and 0.20 from 1 to 2 GHz (PE42820); and 0.80 from 2 to 2.7 GHz (PE42821).
- An ESD of 1.5 kV HBM on all pins.
- A a wide supply range of 2.3 to 5.5 V (PE42820/1).
