摘要
介绍了超外差接收机的基本原理，并给出一种应用于6～18GHz测频接收机射频前端的设计，通过分析其杂散来源介绍了射频前端的混频方案。
This paper introduces the basic principle of the superheterodyne receiver,and gives a de- sign of radio frequency （RF） front-end which is applied to a frequency measurement receiver of 6-18 G Hz,then introduces the mixing scheme by analyzing the clutter sources.
