The RF signal chain is defined by power rather than voltage or current. Providing root-mean-square (RMS) measurement of this power over a wide dynamic range is critical circuit and system requirement.

Modern high-performance transmitters require accurate monitoring of RF power, because most cellular standards depend on strict power- transmission levels to maintain an effective network. Regulation ...

The oldest form of electrical fire detection is the heat detector. Over the years, these devices have had many improvements in their design and operation. The basic method of heat detection still uses ...
