RF Switches

December 1, 2012

Peregrine Semiconductor Corp. (San Diego, CA) offers the HaRP™ SPDT PE42422 RF switch that provides linearity of 115 dBm IIP2, and 70 dBm IIP3, low insertion loss of 0.4 dB @ 3 GHz, and high isolation of 28 dB @ 3 GHz. The switch covers a frequency range of 100 MHz – 6 GHz and, using a nominal +3V power supply voltage, a typical input 0.1 dB compression point of +36 dBm can be achieved. The switch is available in a 2 x 2 mm QFN package, making it suitable for general-purpose RF switching applications such as filter-bank switching in test equipment and base stations.

The 50-Ohm reflective switch features on-chip, low-voltage CMOS control logic and an operating voltage range of 2.3 – 5.5V. It provides ESD performance of 4 kV HBM for RF pin to ground, and low power consumption of 120 microamperes.
