RF Limiter

RFuW Engineering offers a family of passive and quasi-active High Power RF Limiters which operate from HF to X Band frequency ranges with power handling capabilities up to +60 dBm. These RF Limiters provide "Always On" protection which afford complete protection to sensitive RF receivers, even when the system is turned off.
