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

3. Analog passthrough - Wikipedia

   en.wikipedia.org/wiki/Analog_passthrough

   Before digital television, passthrough originally existed in VCRs (and later PVRs and DVDRs) that connected to a TV set using RF connector, allowing the TV antenna or cable TV signal to be switched to pass through the VCR, or have VCR output added as an extra channel.

4. RF switch matrix - Wikipedia

   en.wikipedia.org/wiki/RF_Switch_Matrix

   This custom switch matrix would employ 14 EM switches and a number of different signal conditioners including: power splitters, amplifiers, mixers, filters, and attenuators. RF Switch Matrices are also used heavily in the Television Broadcast market for the reception and re-broadcast of TV Channels.

5. Low-noise block downconverter - Wikipedia

   en.wikipedia.org/wiki/Low-noise_block_downconverter

   Astra type LNBFs incorporate two probes in the waveguide, at right angles to one another so that, once the LNB has been skewed in its mount to match the local polarization angle, one probe collects horizontal signals and the other vertical, and an electronic switch (controlled by the voltage of the LNB's power supply from the receiver: 13 V for ...

6. Radio-frequency microelectromechanical system - Wikipedia

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

   A low loss tangent and low dielectric constant are of importance for the efficiency and the bandwidth of the antenna. 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 ...

7. 8VSB - Wikipedia

   en.wikipedia.org/wiki/8VSB

   Unlike the previous digital TV transition which was mandated by the FCC, the "transition" to ATSC 3.0 will be completely voluntary. Additionally, the FCC has required that broadcasters who decided to make the switch to ATSC 3.0 continue to make their main channel available through a simulcast agreement with another in-market station (with a ...
