Simple RF Detector Circuit using Transistors
Circuit Operation. Working of the circuit is straightforward when the two OA91 germanium diodes get an RF signal thus they convert it into a DC signal. This DC signal is additionally enhanced by the NPN transistor 2N4401 and sends it to the base of the 2N4403 PNP transistor consequently doing it switch ON and enact the bell or buzzer.
