  2. Power dividers and directional couplers - Wikipedia

    en.wikipedia.org/wiki/Power_dividers_and...

    A 10 dB 1.7–2.2 GHz directional coupler. From left to right: input, coupled, isolated (terminated with a load), and transmitted port. A 3 dB 2.0–4.2 GHz power divider/combiner. Power dividers (also power splitters and, when used in reverse, power combiners) and directional couplers are passive devices used mostly in the field of radio ...

  3. Low-noise block downconverter - Wikipedia

    en.wikipedia.org/wiki/Low-noise_block_downconverter

    A Universal LNB has a switchable local oscillator frequency of 9.75/10.60 GHz to provide two modes of operation: low band reception (10.70–11.70 GHz) and high band reception (11.70–12.75 GHz). The local oscillator frequency is switched in response to a 22 kHz signal superimposed on the supply voltage from the connected receiver.

  4. Wilkinson power divider - Wikipedia

    en.wikipedia.org/wiki/Wilkinson_power_divider

    Power divider in microstrip technology. In the field of microwave engineering and circuit design, the Wilkinson Power Divider is a specific class of power divider circuit that can achieve isolation between the output ports while maintaining a matched condition on all ports.

  5. Single-cable distribution - Wikipedia

    en.wikipedia.org/wiki/Single-cable_distribution

    Special LNBs have been developed for use in single-cable distribution systems. All four sub-bands of the Ku band (low frequency/horizontal polarity, high frequency/horizontal polarity, low frequency/vertical polarity, high frequency/vertical polarity) are received by a conventional front end, amplified and downconverted to the L-band, to be fed to a number of SatCR (Satellite Channel Router ...

  6. Passive optical network - Wikipedia

    en.wikipedia.org/wiki/Passive_optical_network

    A beam splitter cannot provide any switching or buffering capabilities and does not use any power supply; the resulting connection is called a point-to-multipoint link. For such a connection, the optical network terminals on the customer's end must perform some special functions which would not otherwise be required.

  7. Diplexer - Wikipedia

    en.wikipedia.org/wiki/Diplexer

    The diplexer is a different device than a passive combiner or splitter. The ports of a diplexer are frequency selective; the ports of a combiner are not. There is also a power "loss" difference - a combiner takes all the power delivered to the S port and equally divides it between the A and B ports. A diplexer does not.

  8. Y-cable - Wikipedia

    en.wikipedia.org/wiki/Y-cable

    A Shure FP24 preamp's mono XLR line outputs connected to an Edirol R-09 recorder's 3.5mm stereo jack line input, using a Y-cable. This is an example of consolidating connectors, as described below.

  9. Fiber-optic splitter - Wikipedia

    en.wikipedia.org/wiki/Fiber-optic_splitter

    The fiber optic splitter is one of the most important passive devices in the optical fiber link. It is an optical fiber tandem device with many input and output terminals, especially applicable to a passive optical network ( EPON , GPON , BPON , FTTX , FTTH etc.) to connect the main distribution frame and the terminal equipment and to branch ...
