RF phase detectors, or radio frequency phase detectors, are useful in a variety of industrial and commercial applications. Many people buy RF phase detectors to use as spy equipment. An RF phase detector can find audio bugs, telephone taps, and also video cameras that may be hidden in a room or on a person.

Other uses for RF and microwave phase detector technology include phase-lock loop applications and data extraction in the telecommunications industry. There are also hand held RF detectors for large industrial equipment and internal detectors that can be installed in computer systems.

To find the right phase loss detectors for your needs, choose a supplier that can supply you with many makes and models of the most common RF phase detection technology. Some product features to consider are:

1. The specific application for the phase loss detector (telecommunications, spy gear, etc.).

2. What type of range the device has.

3. How the device is powered.

Buy RF phase detector technology for phase-lock loops

A phase-lock loop is a term in the telecommunications industry that describes the way devices can extract data and put out multiple frequencies. In order to get a device that works properly with the frequencies available, choose and RF phase detector that can monitor any type of phase-lock loop application.

I recommend: Maxim has an RF phase detector you can use for a variety of telecommunications applications. Global Test Equipment offers products that work specifically with sound.

Choose the RF/IF phase detectors to measure gain and loss in frequencies

RF/IF phase detectors work in combination with many products that need to read very high or very low frequencies. IF stands for intermediate frequency, which is the form a frequency takes between reception and transmission. To detect the best frequency for the product, choose an RF/IF phase detector that can measure gain and loss independently.

I recommend: You can find many RF/IF phase detector options from supply companies like Analog Devices and Mini-Circuits.

Purchase a high band output RF phase detector to find lower frequencies

There are many types of RF phase detectors; but if you need a phase detector that has a high band output, choose from RF phase detector models that have at least a 400mV swing output. Detecting lower frequencies is important for avoiding amplifier saturation, which returns unreliable results.

I recommend: You can find RF phase detectors that have a high band output of 400mV or more from ON Semiconductor. You can also find similar models of RF detectors from NXP Semiconductors.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  The voltage of electronic components is very important. Make sure your RF phase detector has the correct voltage for any products you use it with, otherwise you could create a dangerous situation.
