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°.
