Ultra-Wide Band Power Two Stage Passive Limiter from RFMW


RFLM-200802MA-290 is SMT Silicon PIN Diode Limiter Module offer both High Power CW and PeakPower based on hybrid assembly technique

The RFuW Engineering RFLM-200802MA-299 SMT Silicon PIN Diode Limiter Module offers both High Power CW and Peak Power protection in the 20 MHz to 8 GHz frequency range. It is based on a proven hybrid assembly technique utilized extensively in high reliability, mission critical applications.


The RFLM-200802MA-299 offers excellent thermal characteristics in a compact, low profile 8mm x 5mm x 2.5mm package. The RFLM-200802MA-299 is designed for optimal small signal insertion loss permitting extremely low receiver noise figure while simultaneously offering excellent large input signal Flat Leakage for effective receiver protection in the 20 MHz to 8 GHz frequency range.

The limiter RF circuit characteristics provide outstanding passive receiver protection (always on) which protects against High Average Power up to 44 dBm, High Peak Power up to 51 dBm pulsed (pulse width = 1 usec, duty cycle = 0.1%), maintains low flat leakage to less than 20dBm (typical), and reduces Spike Leakage to less than 0.2 ergs.
