A new high frequency WHF wireless microphone system with substantial improvement in range, versatility and reliability is described. Fading, noise, interference and distortion are eliminated. The transmitter employs fast low distortion audio limiting. The receiver features a dual gate MOS FET front end for low cross modulation and 0.5 microvolt sensitivity. Noise activated squelch improves fade margin by 18 dB.
