2 Simple RF Detector Circuits Explored
If each of the transistor in the diagram is assumed to have a current gain (β) of 150, the total β becomes 150 x 150 x 150 x 150 = 506250000 and the input impedance is potentially 506250000 x 470 ohms, or almost 237937500000 ohms or 237937.5 Mega Ohms.Due to leakage, the above mentioned result might actually not be as high as it appears.
transistors
Here's a simulatable version of the circuit: simulate this circuit – Schematic created using CircuitLab. The key thing to note here is that the charging time constant (when Q1 is cut off) is controlled by R3, and at 220 ms, is much longer than the half-period of the line frequency.
