Abstract
A low cost microwave communication system is described in which a transmitter including an IMPATT diode operating CW (Continuous Wave) is amplitude modulated by a video signal such that the radiated RF (radio frequency) output from the transmitter is directly proportional to the amplitude of the video signal. Low level radiated power from the transmitter is picked up by a receiver which includes a 'square law' detector. The detector provides an output voltage according to the power level of the received RF signal.
