  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. Radio-frequency microelectromechanical system - Wikipedia

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

    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 ...

  4. RF switch matrix - Wikipedia

    en.wikipedia.org/wiki/RF_Switch_Matrix

    The Switch Matrix is made up of discrete electronic components including RF switches and signal conditioners that are mounted together in a mechanical infrastructure or housing. Cables interconnect the switches and signal conditioners. The switch matrix employs a driver circuit and power supply to power and drive the switches and signal ...

  5. Circulator - Wikipedia

    en.wikipedia.org/wiki/Circulator

    ANSI and IEC standard schematic symbol for a circulator (with each waveguide or transmission line port drawn as a single line, rather than as a pair of conductors). In electrical engineering, a circulator is a passive, non-reciprocal three- or four-port device that only allows a microwave or radio-frequency (RF) signal to exit through the port directly after the one it entered.

  6. Butler matrix - Wikipedia

    en.wikipedia.org/wiki/Butler_matrix

    A Butler matrix is a beamforming network used to feed a phased array of antenna elements.Its purpose is to control the direction of a beam, or beams, of radio transmission. ...

  7. Radio transmitter design - Wikipedia

    en.wikipedia.org/wiki/Radio_transmitter_design

    Many transmitters switch in a suitable filter for the frequency band being used. The filter will pass the desired frequency and reduce all harmonics to acceptable levels. The harmonic output of a transmitter is best checked using an RF spectrum analyzer or by tuning a receiver to the various harmonics. If a harmonic falls on a frequency being ...

  8. Automatic test switching - Wikipedia

    en.wikipedia.org/wiki/Automatic_test_switching

    Figure 1D illustrates a double-pole, double throw (DPDT) switch. Contact form, or simply form, is the term relay manufacturers use to describe a relay's contact configuration. "Form A” refers to a single-pole, normally open switch. "Form B" indicates a single-pole, normally closed switch, and "Form C" indicates a single-pole, double-throw switch.

  9. Crossbar switch - Wikipedia

    en.wikipedia.org/wiki/Crossbar_switch

    The switch is operated manually with metal pins that create a connection between the horizontally and vertically arranged bars. [1] In electronics and telecommunications, a crossbar switch (cross-point switch, matrix switch) is a collection of switches arranged in a matrix configuration. A crossbar switch has multiple input and output lines ...
