Richardson RFPD Introduces New 75-Ohm, 5-2200 MHz, RF SPDT Switch From Peregrine

Richardson RFPD

High isolation and low insertion loss for CATV applications

Richardson RFPD, Inc. recently announces immediate availability and full design support capabilities for a new absorptive 75-Ohm RF single-pole, double-throw (SPDT) switch from Peregrine Semiconductor Corporation (Peregrine).

The PE42721 is manufactured on Peregrine’s UltraCMOS process, a patented variation of silicon-oninsulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS. Peregrine’s HaRP technology enhancements provide for new RF architectures and unmatched linearity in RF front end solutions.

The PE42721 operates from 5 to 2200 MHz and is highly linear, delivering high isolation and low insertion loss performance. It supports +1.8V control logic and offers high ESD protection. Additionally, no blocking capacitors are required if DC voltage is not present on the RF ports. It is pin-compatible to Peregrine's PE42750 and is designed to support higher data rates in CATV applications, including CATV signal switching and distribution, DTV, multi-tuner digital video recorders (DVRs) and set-top boxes.

Additional key features of the PE42721 include:

  • High linearity
    • CTB of -99 dBc
    • CSO better than -105 dBc
  • Low insertion loss
    • 0.40 dB @ 220 MHz
    • 0.50 dB @ 870 MHz
    • 0.65 dB @ 2200 MHz
  • High isolation
    • 85 dB @ 220 MHz
    • 68 dB @ 870 MHz
    • 53 dB @ 2200 MHz
  • ESD performance
    • 3kV HBM on RF pins to GND
    • 2kV HBM on all other pins
    • 1kV CDM on all pins
