Geneva, IL. Richardson RFPD Inc. has announced the availability of and full design support capabilities for a new power limiter from Peregrine Semiconductor Corp. The UltraCMOS PE45361 builds on Peregrine’s 50-W 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, 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 nonlimiting power levels and extremely fast response time in a limiting event, ensuring protection of sensitive circuitry. It also offers 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 of +50 dBm, 100-W pulsed;
- positive threshold control, from +0 V to +0.3 V;
- response time < 1 ns; and
- 12-lead, 3 x 3 x 0.5-mm QFN packaging.
