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).
An RF switch matrix is an array of RF switches arranged to route radio frequency (RF) signals between multiple inputs and multiple outputs. Applications requiring RF matrices include ground systems, test equipment, and communication systems.
(b) An ohmic cantilever RF MEMS switch, connected in series to a microstrip line. A radio-frequency microelectromechanical system (RF MEMS) is a microelectromechanical system with electronic components comprising moving sub-millimeter-sized parts that provide radio-frequency (RF) functionality. [1]
Basic automatic frequency control in a radio receiver. У = RF amplifier stages, Д = frequency discriminator stage. In radio equipment, Automatic Frequency Control (AFC), also called Automatic Fine Tuning (AFT), is a method or circuit to automatically keep a resonant circuit tuned to the frequency of an incoming radio signal.
An RF modulator (radio frequency modulator) is an electronic device used to convert signals from devices such as media players, VCRs and game consoles to a format that can be handled by a device designed to receive a modulated RF input, such as a radio or television receiver.
The modules include a new line of reflective RF switch modules that reportedly last 1,000 times longer than traditional RF electromechanical relays.
