Rf Detector Circuit Diagram. Here is an improved version of the rf detector circuit that we have discussed previously. The circuit is using only few components which are two diodes oa91 two transistors one 10k resistor and a buzzer.
The circuit appeared here can be utilized to distinguish a wide band of rf signals and give a caution when it will detect an rf signal. This rf detector circuit is designed based on transistors and common electronic components. But i want to power up a rf detector circuit with 12v detect signals of about 433mhz 400mhz 500mhz and give a sound during detection.
I want to do something similar.
It consists of a telescopic antenna input protection resistor r1 two diodes d1 and d2 selector switch s1 pre amplifier with a low noise and high gain transistor t1 and audio amplifier ic lm386 ic1. Hi sir excellent work.
