RF power detectors are not a specific brand but a category of electronic components used to measure radio frequency (RF) signal power. These devices are produced by various global companies, such as Analog Devices (USA), Keysight Technologies (USA), and Mini-Circuits (USA), serving industries like telecommunications, aerospace, and test & measurement. Key products include logarithmic amplifiers, diode-based detectors, and integrated RF power monitoring ICs, enabling precise signal analysis in wireless systems, radar, and 5G infrastructure.
