Original Press Release:

Richardson RFPD Introduces New 100-Watt RF SOI Power Limiter from Peregrine

Delivers reliable and repeatable power protection

Richardson RFPD, Inc. announced today the availability and full design support capabilities for a new power limiter from Peregrine Semiconductor Corporation.

The UltraCMOS® PE45361 builds on the success of Peregrine's 50-watt UltraCMOS power limiters and adds higher pulsed power handling, a lower limiting threshold and positive threshold control. The PE45361 delivers reliable and repeatable power protection to sensitive low-noise receivers for test-and-measurement equipment and wireless-infrastructure transceivers

Unlike traditional PIN diode solutions, the PE45361 achieves an adjustable input 1 dB compression point or limiting threshold via a low current control voltage (VCTRL), eliminating the need for external bias components such as DC blocking capacitors, RF choke inductors and bias resistors.

The new limiter delivers low insertion loss and high linearity under non-limiting power levels and extremely fast response time in a limiting event, ensuring protection of sensitive circuitry. It also offers excellent ESD rating and ESD protection.

The PE45361 is manufactured on Peregrine’s UltraCMOS® process, a patented advanced form of silicon-on-insulator (SOI) technology, offering the performance of GaAs with the economy and integration of conventional CMOS.

Additional key features of the PE45361 include:

  • Adjustable low power limiting threshold: from +7 dBm to +13 dBm
  • Maximum power handling: +50 dBm, 100 W pulsed
  • Positive threshold control: from +0 V to +0.3 V
  • Response time: < 1 ns
  • Packaging: 12-lead, 3 mm x 3 mm x 0.5 mm QFN
