An DIY RF decibel (or power) meter is an indispensable instrument in any radio workshop. Unfortunately, accurate, wideband models are fairly expensive, and home-constructed ones are generally not ...

While LCR meters are readily available at reasonable cost, they do not measure the Q of an inductor. This circuit enables you to measure the Q of inductors with the aid of an RF signal generator. A ...

When thermistors are subjected to an RF input, they warm up and their resistance drops, which can be accurately measured in a bridge circuit. Drawbacks of thermistors include low RF measurement ...

There is a basic method for measuring high-frequency power using a power meter and power sensor (Fig. 1). The power sensor converts high-frequency power to a dc or low-frequency signal that the power ...

The output power of an RF or microwave system is a key determinant of its performance. For this reason, signal power is measured at every stage of a system’s lifecycle from the design and prototyping ...
