Abstract : The signal-to-noise enhancer is a passive two-port device which performs the function opposite that of the frequency selective microwave power limiter. Incoming signals falling below some threshold power level suffer insertion loss up to 30 dB or more. Signals exceeding the threshold, which is on the order of 1 mW, are attenuated by a significantly smaller amount. The difference in insertion loss cn be more than 25 dB for signals 20 dB or more above threshold.
