摘要

本文设计了一种用于上下转换混频器的s波段混频器电路。所提出的混频器工作在-20dBm到- 3dbm的功率电平范围内，用于下变频器的射频输入和上变频器的中频输入。本振(LO)工作在2.87 GHz，功率电平为+2dBm。仿真和测量表明，转换损耗大于-10dB, RF、IF和LO端口之间具有良好的隔离性(RF-LO隔离>30 dB, LO-IF隔离>30 dB, RF-IF隔离>25 dB)。

Design and implement a single balanced mixer at S band

In this paper, an S-band mixer circuit used for both up- and down- conversion mixers is designed. The proposed mixer works in the range power levels from -20dBm to -3 dBm for the RF input of the down-converter, and for the IF input of the up-converter. The Local oscillator (LO) working at 2.87 GHz has the power level of +2dBm. The simulation and measurement exhibits the conversion loss greater than -10dB and good isolation between RF, IF, and LO ports (RF-LO isolation >30 dB, LO-IF isolation>30 dB, RF-IF isolation>25 dB).
