2. Miniature snap-action switch - Wikipedia

   en.wikipedia.org/wiki/Miniature_snap-action_switch

   In 1937 W.B. Schulte, [2] McGall's employer, started the company MICRO SWITCH. The company and the Micro Switch trademark have been owned by Honeywell Sensing and Control since 1950. [3] The name has become a generic trademark for any snap-action switch. Companies other than Honeywell now manufacture miniature snap-action switches.

3. RF switch - Wikipedia

   en.wikipedia.org/wiki/RF_switch

   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). Incorporating a switch into a switch matrix system enables you to route signals ...

4. Radio-frequency microelectromechanical system - Wikipedia

   en.wikipedia.org/wiki/Radio-frequency_micro...

   A capacitive fixed-fixed beam RF MEMS switch, as shown in Fig. 1(a), is in essence a micro-machined capacitor with a moving top electrode, which is the beam. It is generally connected in shunt with the transmission line and used in X- to W-band (77 GHz and 94 GHz) RF MEMS components. An ohmic cantilever RF MEMS switch, as shown in Fig. 1(b), is ...

5. Monolithic microwave integrated circuit - Wikipedia

   en.wikipedia.org/wiki/Monolithic_microwave...

   Monolithic microwave integrated circuit, or MMIC (sometimes pronounced "mimic"), is a type of integrated circuit (IC) device that operates at microwave frequencies (300 MHz to 300 GHz). These devices typically perform functions such as microwave mixing , power amplification, low-noise amplification , and high-frequency switching.

6. Microwave radiometer - Wikipedia

   en.wikipedia.org/wiki/Microwave_radiometer

   A microwave radiometer consists of an antenna system, microwave radio-frequency components (front-end) and a back-end for signal processing at intermediate frequencies. The key element is the Dicke switch, which alternately switches between the antenna and a cryogenic load at a known temperature.
