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 ...

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 ...

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 ...

Typical applications include in-circuit RF power monitoring at RF power levels up to 30 dBm, where insertion loss isn’t critical. The return-loss measurement capability is typically used in ...
