RF Detectors

RF (radio frequency) detectors are electronic circuits that are used to detect the presence of an RF signal. These detectors are typically used in applications where it is necessary to know whether an RF signal is present, such as in radio and television receivers, wireless communication systems, and radar systems. RF detectors may be passive or active, depending on the design of the circuit. Passive RF detectors are simpler and less expensive, but have lower sensitivity and may not be able to detect weak signals. Active RF detectors typically use an amplifier to boost the signal, increasing sensitivity and allowing them to detect weaker signals. RF detectors are an essential component of many electronic systems, providing a means of detecting the presence of an RF signal.
