This project is very useful for the radio frequency (rf) engineer and hobbyist, especially when the final rf transmission has to adjusted . Setting up an antenna impedance matcher is one example. Here is the schematic diagram of this rf meter circuit: |
|
D-I-Y Project |
|
The circuit uses a single transistor (MPSA18) as the active component. The signal strength meter display uses an analog meter (1 mA full scale) . This rf field strength meter has no scale. The important thing for this uncalibrated rf meter is that it can display the changes of an rf field when we calibrate the antenna or the matching network for the rf transmitter-antenna loading. If we are tuning the antenna size or the transmitter-antenna matcher filter, then just observe the analog meter to get maximum deflection. Look at the transistor circuit, the base of the transistor is not biased by the voltage from the power supply. It is directly driven by the signal from the rectified received rf signal. It means that the circuit won’t draw any current from battery if there’s no received rf signal, so it doesn’t need a power switch to cut the power consumption of the supply (the battery), just make sure to move it away from strong active rf transmitter when this device is not in use.
