RF Spy Bug Detector Circuit. May 23, 2013 by P. Marian Comments 8. Advertisement. Here is a simple RF bug detector that will help you detect spy bugs and can operate up to 2 GHz. Below are some ...

Figure 1 shows a waveform-independent circuit that provides a linear measurement of RF power. Sophisticated modulation schemes, such as CDMA (code-division multiple access) and TDMA (time-division ...

Such a circuit includes a rectifying diode, filter capacitor, resistor, and possibly an RF choke and a second capacitor. The two simplest detector circuits are half-wave rectifiers.

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 ...

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 … ...

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 ...
