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 ...
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 ...

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 ...
RF CMOS circuits are widely used to transmit and receive wireless signals in a variety of applications, such as satellite technology (such as GPS), Bluetooth, Wi-Fi, near-field communication (NFC), mobile networks (such as 3G, 4G, and 5G), terrestrial broadcast, and automotive radar applications, among other uses.

Examples of radio frequency analog hardware switch or RF switch technologies are high voltage vacuum relays [6] or high power semiconductor PIN diode switches. In recent times, as PIN diode power handling capabilities have been improved by the semiconductor industry, PIN diodes have largely supplanted vacuum relays in the QSK switch function ...
