Abstract
A communication system includes a passive quadrature generator connected directly to an in-phase (I) mixer and a quadrature (Q) mixer, an I LO amplitude detect circuit connected to the passive quadrature generator and connected to the I mixer, and a Q LO amplitude detect circuit connected to the passive quadrature generator and connected to the Q mixer, the I LO amplitude detect circuit configured to detect an I LO amplitude and the Q LO amplitude detect circuit configured to detect a Q LO amplitude, and a combining and integrating circuit configured to receive the detected I LO amplitude and the detected Q LO amplitude and generate an I LO DC bias voltage to bias the I mixer and a Q LO DC bias voltage to bias the Q mixer.
