Abstract
An electronic circuit can include a gain adjustment circuit (e.g., a gain 'equalizer' circuit), such as to compensate for a variation in insertion loss over a specified range of frequencies. For example, such a gain adjustment circuit can provide an insertion loss characteristic having a specified slope. Such a slope can include a positive slope where insertion loss increases with respect to frequency, or a negative slope where insertion loss decreases with respect to frequency, as illustrative examples. A gain equalization technique can be used to compensate for variation in insertion loss versus frequency between different circuit paths, such as in relation to a switchable delay line having two or more selectable paths, such as for phase shifting applications. A gain adjustment circuit can be configured to provide relatively flat or constant time-domain delay versus frequency, such as inhibiting or reducing dispersion.
