2. 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).

3. RF switch matrix - Wikipedia

   en.wikipedia.org/wiki/RF_Switch_Matrix

   There are six main challenges when designing a custom RF/Microwave Switch Matrix from beginning to end: Mechanical Design: design of an electrically shielded enclosure or box, internal component mounting brackets, with a component and cabling layout. RF/Microwave Design: a signal routing and signal conditioning design and testing plan. A ...

   The prior art includes an RF MEMS frequency tunable fractal antenna for the 0.1–6 GHz frequency range, [18] and the actual integration of RF MEMS switches on a self-similar Sierpinski gasket antenna to increase its number of resonant frequencies, extending its range to 8 GHz, 14 GHz and 25 GHz, [19] [20] an RF MEMS radiation pattern ...

6. RF modulator - Wikipedia

   en.wikipedia.org/wiki/RF_modulator

   ASTEC UM 1286 UHF modulator, top cover taken off. 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.

7. In-circuit testing - Wikipedia

   en.wikipedia.org/wiki/In-circuit_testing

   A common form of in-circuit testing uses a bed-of-nails tester.This is a fixture that uses an array of spring-loaded pins known as "pogo pins". When a printed circuit board is aligned with and pressed down onto the bed-of-nails tester, the pins make electrical contact with locations on the circuit board, allowing them to be used as test points for in-circuit testing.
