- Enables high-peak power handling and fast recovery times
- Also offers “always-on” protection in a compact form factor
The SMT Silicon PIN Diode Limiter, RFLM-102402QF-290 from RFuW Engineering offers both high power CW and peak power protection across the L & S-Band region (1 to 4 GHz). It is based on a hybrid assembly technique utilized extensively in high reliability, mission-critical applications.
Capable of handling average power up to 100 Watts (50 dBm) and pulsed peak power up to 1,000 Watts (60 dBm at pulse width = 25 usec, duty cycle = 5%), the RFLM-102402QF-290 maintains low flat leakage to less than 14 dBm and reduces spike leakage to less than 0.5 ergs. Recovery time is <3 uSec. The combination of high peak power handling and fast recovery time is mandatory for mission-critical applications.
RF performance with an insertion loss of less than 0.35 dB makes the module optimal for small-signal insertion loss permitting extremely low receiver noise figure. This quasi-active limiter requires no external control lines or power supply connections offering “always-on” protection.
The RFLM-102402QF-290 offers excellent thermal characteristics in a compact 8 mm x 5 mm x 2.5 mm ceramic surface mount package and is now available from RFMW.
