100 Watt S-Band Power Limiter

RFMW announces design and sales support for a high power, SMT RF limiter. The RFuW Engineering model number RFLM-011015QF-290, silicon, PIN-Diode limiter module offers both high power CW and peak power protection in the 2 to 4 GHz frequency range. Capable of handling average power up to 100 Watts (50 dBm) and pulsed peak power up to 250 Watts (54 dBm at pulse width = 1 msec, duty cycle = 10%), the RFLM-011015QF-290 maintains low flat leakage to less than 14 dBm (typical), 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 is exceptional with insertion loss of less than 0.5 dB for most of the bandwidth. This quasi-active limiter requires no external control lines or power supply connections offering “always on” protection. Offered in a 8 x 5 x 2.5 mm, ceramic surface mount package.
