With the use of double balance mixer structure, we achieved wideband impedance match at RFport and selected appropriate switch signal at LO port.
采用双平衡混频结构进行设计,在射频端口实现宽带阻抗匹配,在本振端口选取合适的开关信号。

The LO phase noise, LO-RFport isolation of the mixer in the front-end and their effect on the detectability of the radiometer were analyzed in this paper.
