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.

What is an RF detector? An RF detector monitors or samples the output of an RF circuit and develops a dc output voltage proportional to the power at that point. What do you do ...

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 ...

The LMV221 RF power detector from National Semiconductor Corp., Santa Clara, Calif., targets mobile-phone power controls in current and emerging cellular standards, including ...

In this paper, we discuss the design of an RF IC detector with eight channels connected to the package pins, designed to determine the incident RF power on each pin. Some of these channels possess ...

The first of a two-volume set, this leading-edge book takes a practical approach to RF circuit design, offering a complete understanding of the fundamental concepts you need to know and use for your ...

Analog Devices has its first dual-channel radio frequency root-mean-square (rms) power detector for precision measurement of transmit and receive signals up to 2.7GHz. The AD8364 is designed to ...

In fact, [Sebastian] even used literature from the triode version of this detector to figure out the values for some of the components. The only active component is a BF256B JFET; the rest are a ...
