RFLM-262322HC-151 – Limiter

SKU: P193 Category:

The RFLM-262322HC-151 SMT Silicon PIN Diode Limiter Module offers “Always On” High Power CW and Peak protection in the S-Band region. This Limiter Modules are based on proven hybrid assembly technique utilized extensively in high reliability, mission critical applications. The RFLM-262322HC-151 offers excellent thermal characteristics in a compact, low profile 6mm x 9mm x 2.5mm package. They 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 S Band frequency range.
The RFLM-262322HC-151 Limiter Module provides outstanding passive receiver protection (Always on) which protects against High Average Power up to +48 dBm @ Tcase=+85oC, High Peak Power up to +57 dBm (Peak) Pulse Width = 25 usec, Pulse Repetition Rate = 5%, Tcase=+85oC, maintains low flat leakage to less than 14 dBm (typ), and reduces Spike Leakage to less than 0.5 ergs(typ).
