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 ...
A match is good if the return loss is high. A high return loss is desirable and results in a lower insertion loss. From a certain perspective 'Return Loss' is a misnomer. The usual function of a transmission line is to convey power from a source to a load with minimal loss. If a transmission line is correctly matched to a load, the reflected ...
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).
In telecommunications, insertion gain is the gain resulting from the insertion of a device in a transmission line, expressed as the ratio of the signal power delivered to that part of the line following the device to the signal power delivered to that same part before insertion. Gains less than unity indicate insertion loss. Incident power is ...
Coupling loss is usually expressed in the same units—such as watts or decibels—as in the originating circuit element or medium. [1] Coupling loss in fiber optics refers to the power loss that occurs when coupling light from one optical device or medium to another. (See also Optical return loss.) Coupling losses can result from a number of ...
The loss tangent is defined by the angle between the capacitor's impedance vector and the negative reactive axis. If the capacitor is used in an AC circuit, the dissipation factor due to the non-ideal capacitor is expressed as the ratio of the resistive power loss in the ESR to the reactive power oscillating in the capacitor, or
Insertion, several meanings in medicine, see ICD-10-PCS; Insertion loss, in electronics; Insertion reaction, a chemical reaction in which one chemical entity interposes itself into an existing bond of a second chemical entity (e.g.: A + B–C → B– A –C) Insertion sort, a simple computer algorithm for sorting arrays; Local insertion, in ...
Bridging loss, the loss that results when an impedance is connected across a transmission line; Coupling loss, the loss that occurs when energy is transferred from one circuit, optical device, or medium to another; Insertion loss, the decrease in transmitted signal power resulting from the insertion of a device in a transmission line or optical ...
