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 ...

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 ...

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 ...

This paper describes the design of an RF power detector which has broad bandwidth and high dynamic range. The proposed RF power detector includes a low noise amplifier (LNA), limiting amplifiers, a ...

That’s the premise behind [RamboRogers]’ RF hunter, the spy movie electronic scanner made real. At the rear of the device is an ESP32, but the front end is an AD8317 RF detector chip.

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 ...

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.

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 ...
