研究背景本文略述一般的平衡混频器电路,并特别讨论将两个射频输入信号混频产生音频或射频输出信号的平衡双输出二极管混频器电路。平衡混频器电路通常也属于环形调制器电路。通常它包含二个变压器和二极管或其他开关型网络。变压器的次级绕组均有中心抽头,而二极管或其他开关型网络则耦合于有中心抽头的绕组之间。典型的方式是第一个射频信号激励第一级变压器的初级绕组,第二个射频 Background This article outlines a general balanced mixer circuit and in particular discusses a balanced dual output diode mixer circuit that mixes two radio frequency input signals to produce either audio or radio frequency output signals. Balanced mixer circuits also typically belong to ring modulator circuits. It usually contains two transformers and diodes or other switched networks. Transformer secondary windings have center taps and diodes or other switched networks are coupled between center tapped windings. The typical way is that the first RF signal excites the primary winding of the first transformer and the second RF
