Abstract:
A bidirectional radio frequency amplifier which includes a power amplifier and a receiver amplifier connected to a common antenna. A pair of parallel diodes coupled across the input of the receiver amplifier provides a high impedance path for a received signal and a low impedance path during transmission thereby eliminating the need for mechanical or semiconductor switching.
A relatively simple, inexpensive, effective circuit for detecting overdriving of a radio frequency amplifier by an amplitude modulated signal. The input and output signals of the amplifier are coupled to peak detectors. A light emitting diode which provides a visual indication of the overdrive condition is coupled between the peak detectors.
