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 ...
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 ...

Also capable of supporting 10GE ports. 20 or 44 10/100 port switches with two models supportingPoE functionality, and 4 x Dual Personality Ports (2 x Gb or SFPs). [4] [5] 20 or 44 Gb port switch with PoE functionality, and 4 x Dual Personality Ports (2 x Gb or SFPs).
An RF power amplifier is tuned to a single frequency as low as 18 kHz and as high as the UHF range of frequencies, for the purpose of radio transmission or industrial heating. They use a narrow tuned circuit to provide the valve with a suitably high load impedance and feed a load that is typically 50 or 75 Ohms.
Fig. 1: The power devices family, showing the principal power switches. A power device may be classified as one of the following main categories (see figure 1): A two-terminal device (e.g., a diode), whose state is completely dependent on the external power circuit to which it is connected.
Radio frequency (RF) and microwave filters represent a class of electronic filter, designed to operate on signals in the megahertz to gigahertz frequency ranges (medium frequency to extremely high frequency). It is component that is used in electronic systems to pass or reject specific frequencies and attenuate of unwanted signals within the ...
Telecommunications equipment (also telecoms equipment or communications equipment) is a type of hardware which is used for the purposes of telecommunications.Since the 1990s the boundary between telecoms equipment and IT hardware has become blurred as a result of the growth of the internet and its increasing role in the transfer of telecoms data.
