A microwave power meter is an instrument which measures the electrical power at microwave frequencies typically in the range 100 MHz to 40 GHz.. Usually a microwave power meter will consist of a measuring head which contains the actual power sensing element, connected via a cable to the meter proper, which displays the power reading.
A water flow test, also known as a hydrant flow test, [1] is a way to measure the water supply available at a building site, usually for the purposes of installing a water based fire protection system (fire sprinkler system). The most common test involves measuring the flow of water flowing out of a municipal fire hydrant (measured in litres or ...
An RF switch or microwave switch is a device to route high frequency signals through transmission paths. RF (radio frequency) and microwave switches are used extensively in microwave test systems for signal routing between instruments and devices under test (DUT). Incorporating a switch into a switch matrix system enables you to route signals ...
The microwave engineering discipline has become relevant as the microwave domain moves into the commercial sector, and no longer only applicable to 20th and 21st century military technologies. Inexpensive components and digital communications in the microwave domain have opened up areas pertinent to this discipline.
Microwave is executed non-contact technique or guided. The first is done by monitoring a microwave signal that is transmitted through free space (including vacuum) and reflected back, or can be executed as a "radar on a wire" technique, generally known as guided wave radar or guided microwave radar.
A microwave radiometer consists of an antenna system, microwave radio-frequency components (front-end) and a back-end for signal processing at intermediate frequencies. The key element is the Dicke switch, which alternately switches between the antenna and a cryogenic load at a known temperature.

Microwave relay stations were often located on tall buildings and mountaintops, with their antennas on towers to get maximum range. Beginning in the 1950s, networks of microwave relay links, such as the AT&T Long Lines system in the U.S., carried long-distance telephone calls and television programs between cities. [1]
