Power Limiter Module For Mission Critical Applications

  • Offers very low-flat leakage under high power conditions
  • Has a fast recovery time of 1.5 usec

RFuW Engineering’s, a provider of RF and microwave power products, introduces RFLM-052402QC-290 SMT Silicon PIN Diode Limiter Modules. It is designed for small signal insertion loss for extremely low receiver noise while simultaneously offering very low flat leakage under high power conditions. It thereby offers excellent receiver protection across the 50 MHz to 4.0 GHz frequency range.

Along with that, the module offers outstanding passive receiver protection (Always on) against High Average Power of up to +53 dBm or 200 Watts (CW) and high peak power of up to +63 dBm at pulse width = 25 usec, duty cycle = 5% or 2000 Watts , while maintaining low flat Leakage to less than 17dBm and reduces spike leakage to less than 0.5 ergs.

This combination of high peak power handling and fast recovery time of 1.5 usec is essential for mission-critical applications.



The RFLM-052402QC-290 offers excellent thermal characteristics in a compact, low profile 8mm x 5mm x 2.5mm package.
