Richardson RFPD Introduces New 10 MHz to 8 GHz UltraCMOS? SP4T Switch from Peregrine
LaFOX, IL - Richardson RFPD, Inc. announced today the availability and full design support capabilities for a new RF single-pole four-throw (SP4T) switch from Peregrine Semiconductor Corporation.

The broadband PE42441 operates from 10 MHz to 8 GHz and features four symmetric RF ports, low insertion loss (0.8 dB at 3 GHz), exceptional isolation (45 dB), high power handling (+31 dBm P0.1dB), and +58 dBm IIP3 at 8 GHz. An on-chip CMOS decode logic facilitates a two-pin voltage CMOS control interface. In addition, no external blocking capacitors are required if 0VDC is present on RF ports.

The PE42441 is manufactured on Peregrine's UltraCMOS® process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS.

According to Peregrine, additional key features of the PE42441 include:

  • High isolation
    • 45 dB @ 3 GHz
    • 39 dB @ 6 GHz
    • 31 dB @ 8 GHz
  • Low insertion loss
    1. o0.8 dB @ 3 GHz
    2. o1.0 dB @ 6 GHz
    3. o1.2 dB @ 8 GHz
  • High linearity
    • +58 dBm IIP3 @ 8 GHz
    • +110 dBm IIP2 @ 8 GHz
  • 1.8V control logic compatible
  • 5 µs switching time
  • ESD performance
    • 2kV HBM on all pins
    • 100V MM on all pins
    • 1 kV CDM on all pins
