正交混波器电路

Quadrature mixer circuit

Abstract

The present invention relates to a mixer which includes a polyphase filter that generates linear quadrature signals. The mixer also includes a potentiometric mixer that performs a frequency-conversion operation on the quadrature signal. According to the present invention, the output of the potentiometric mixer has high linearity.
本发明提供一种混波器。该混波器包含多相滤波器,用来产生线性的正交信号;以及电位混波器,用来对该正交信号执行频率转换操作;其中,该电位混波器的输出信号具有高线性度。
