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 ...

From primitive crystal detectors to today's advanced exponential logarithmic amplifiers, RF power detection has come a long way.

Modern high-performance transmitters require accurate monitoring of RF power, because most cellular standards depend on strict power- transmission levels to maintain an effective network. Regulation ...

This handheld radio has a little secret. You’re not going to be able to listen to Limbaugh since the original FM tuning circuit has been removed and replaced by a diode detector. Now [Miguel … ...

Spin-torque diodes enable the detection and rectification of radiofrequencies by means of spin-torque-induced ferromagnetic resonance between nanomagnets. Now, by using magnetic tunnel junctions ...

The CPDETLS-4000 RF power detector suits low-cost RF power monitoring in general lab use. With a frequency range of 10 MHz to 4 GHz, it is a zero-bias Schottky diode intended for use as a large ...

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 ...
