摘　　要：介绍了一种6～18GHz小型化正交混频器。该正交混频器在所要求的频率范围内达到以下性能指标：变频损耗优于10dB，典型值8dB；镜像抑制度优于18dB，典型值25dB；LO到RF、RF到IF的隔离优于25dB，LO到IF的隔离优于20dB，典型值均为30dB。同时，测试结果表明该混频器具有良好的可靠性和一致性。A kind of 6 - 18GHz miniature IQ mixer has been introduced. During the requested frequency range, the proposed IQ mixer has conversion losses less than lOdB, typical value of 8 dB, Image reject greater than 18dB, typical value of 25 dB, LO-to-RF and RF-to-IF isolation greater than 25dB while LO-to-IF isolation greater than 20dB, with all three has typical value of 30dB. Also its good reliability and consistency is showed according to measurement result.
