Abstract : The patent concerns an amplitude modulation detection apparatus utilizing a balanced diode rectifier circuit to detect amplitude modulation on HF and VHF amplitude modulated carrier frequencies at rates approaching to the carrier frequency without diagonal clipping. A temperature compensating forward biasing supply circuit is connected to the rectifier circuit to supply thereto a forward bias potential that varies with temperature and a trickle current that remains substantially independent of temperature variation.
