摘要
针对宽带发射系统对低杂散信号的需求,提出了一种基于偏置电压校正的载波抑制方法。采用正交调制器作为混频器,通过对其基带偏置电压进行校正,使载波泄漏最小,从而达到低杂散。
In this work, a method based on biasing voltage calibration has been proposed to satisfy the requirement of low spurious for wideband transceiver. The developed method employs a quadrature modulator as the mixer, and calibrates the baseband biasing voltage of the mixer to minimize the leakage of carrier, then fulfills the demand of low spurious.
