RF Power Sensors
An RF power sensor is a device that is used to measure the power of an RF (radio frequency) signal. RF power sensors are used in a variety of applications, including telecommunications, broadcasting, aerospace, and defence.
The basic principle behind an RF power sensor is to convert the power of an RF signal into an electrical signal that can be measured. This is typically done using a detector that is sensitive to RF signals, such as a thermocouple or diode. The detector converts the RF power into a DC voltage, which is proportional to the RF power level. This DC voltage is then measured and converted into a digital signal that can be processed by a computer or other device.
RF power sensors come in a variety of types and designs, including directional and non-directional sensors, broadband and narrowband sensors, and thermal and non-thermal sensors. The choice of sensor depends on the specific application and the characteristics of the RF signal being measured.
