RFMW announced design and sales support for a high power, SMT RF limiter. The RFuW Engineering model RFLM-102402QF-290, silicon, PIN-Diode limiter module offers both high power CW and peak power protection in the L & S-Band region (1 to 4 GHz). Capable of handling average power up to 100 W (50 dBm) and pulsed peak power up to 1,000 W (60 dBm at pulse width = 25 usec, duty cycle = 5 percent), the RFLM-102402QF-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 0.35 dB. 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.
