摘要： A phase shifter component is described. Inputs are arranged to selectively receive an inphase component of an in-phase (I) signal or an outphase I signal 180° out of phase with the inphase I signal, and to selectively receive an inphase component of a quadrature-phase (Q) signal or an outphase Q signal 180° out of phase with the inphase Q signal. A first gain portion includes only two transistor elements arranged to amplify the received outphase or inphase I signal. A second gain portion includes only two transistor elements arranged to amplify the received outphase or inphase Q signal. The first and second gain portions are configured to control the gain of the received outphase or inphase I signal and the received outphase or inphase Q signal, respectively, to provide a composite output signal with a desired phase shift between 0° and 360°.

摘要： A circuit includes an electrical gain element, a variable reactance element, and a controller. The electrical gain element is arranged to receive and change an amplitude of a signal over a set frequency range. The variable reactance element is connected to the electrical gain element. The controller is configured to control the variable reactance element to have a reactance such that the electrical gain element has a set gain slope as a function of signal frequency over the set frequency range.
