  2. Insertion loss - Wikipedia

    en.wikipedia.org/wiki/Insertion_loss

    In telecommunications, insertion loss is the loss of signal power resulting from the insertion of a device in a transmission line or optical fiber and is usually expressed in decibels (dB). If the power transmitted to the load before insertion is P T and the power received by the load after insertion is P R , then the insertion loss in decibels ...

  3. Power dividers and directional couplers - Wikipedia

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

    The insertion loss is not such a problem for an unequal split of power: for instance -40 dB at port 3 has an insertion loss less than 0.2 dB at port 2. Isolation can be improved at the expense of insertion loss at both output ports by replacing the output resistors with T pads. The isolation improvement is greater than the insertion loss added ...

  4. Scattering parameters - Wikipedia

    The extra loss may be due to intrinsic loss in the DUT and/or mismatch. In case of extra loss the insertion loss is defined to be positive. The negative of insertion loss expressed in decibels is defined as insertion gain and is equal to the scalar logarithmic gain (see: definition above).

  5. Duplexer - Wikipedia

    en.wikipedia.org/wiki/Duplexer

    Isolation typical >75 dB Insertion Loss typical < 1.0 dB. Note 1: A duplexer must be designed for operation in the frequency band used by the receiver and transmitter, and must be capable of handling the output power of the transmitter.

  6. Galvanic isolation - Wikipedia

    en.wikipedia.org/wiki/Galvanic_isolation

    Galvanic isolation is a principle of isolating functional sections of electrical systems to prevent current flow; no direct conduction path is permitted. [ 1 ] [ 2 ] Energy or information can still be exchanged between the sections by other means, such as capacitive , inductive , radiative , optical , acoustic , or mechanical coupling.

  8. RF switch - Wikipedia

    en.wikipedia.org/wiki/RF_switch

    A low insertion loss system can be achieved by minimizing the number of connectors and through-paths, or by selecting low insertion loss devices for system configuration. As power is expensive at higher frequencies, electromechanical switches provide the lowest possible loss along the transmission path.
