Here is a simple RF bug detector that will help you detect spy bugs and can operate up to 2 GHz. Below are some essential things required for this circuit: to cover a large frequency band make a sound ...

This simple circuit helps you sniff out RF radiation leaking from your transmitter, improper joints, a broken cable or equipment with poor RF shielding. The tester is designed for the 2-m amateur ...

There is schematic diagram, PCB layout and 3D View. From there you can print and solder your own RF detector circuit.","The range of detection is based on the commponents used and the strenght of the ...

From primitive crystal detectors to today's advanced exponential logarithmic amplifiers, RF power detection has come a long way. Many systems need to measure radio frequency (RF) power. Some ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors ...

The power detector achieves a ±0.5-dB temperature-stable linear-in-dB response at operating temperatures from −40° to +85°C. The power detector draws 70 mA current from a +5-VDC supply.

The HMC1020LP4E and HMC1021LP4E RMS power detectors are suitable for broadband, highdynamic- range applications requiring repeatable measurement of average signal power; especially where detection of ...

To simplify the detector electronics, we initiate a multiplexing concept based on RF transformers. This approach may reduce the signal-processing channels by a factor of 16 (from 64 channels to four).
