Peregrine Semiconductor Expands Family of High-Linearity, Low Insertion Loss SPDT RF Switches

Peregrine PE42422

PE42422 addresses portable wireless and general-purpose RF applications with 100 MHz – 6 GHz operation and 2 × 2 mm package

Peregrine Semiconductor Corporation announced the expansion of its high-linearity, low insertion loss RF switch family with the availability of the HaRP™ technology-enhanced SPDT PE42422 RF switch. The new switch 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, enabling better overall system performance. The switch covers a wide 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 PE42422 switch is available in a space-saving 2 × 2 mm QFN package, making it well suited for general-purpose RF switching applications, such as filter-bank switching in test equipment and base stations.

The 50 Ohm, reflective PE42422 switch features on-chip, low-voltage CMOS control logic and a wide operating voltage range of 2.3 – 5.5V, enabling it to be used it in a variety of ways. ESD performance of 4 kV HBM for RF pin to ground simplifies manufacturing and improves product reliability. Additionally, with low power consumption of 120 microamperes (typical), the PE42422 switch helps to extend battery life in portable devices.
