Insertion loss
The insertion loss (engl. Insertion Loss , IL ) is the attenuation of a signal at by a member which is inserted in a signal path. This can be a passive filter or a plug connection , for example .
The insertion loss describes the relationship between the incident power (on the component) and the power transmitted . Since the insertion loss is given in dB , the following formula is used:
With filters and couplers , the insertion loss is usually determined depending on the frequency range of the useful signal .
The insertion loss can also be expressed using the scattering parameters (S parameters) as:
