8mm集成环形倒扣混频器设计和研制

DESIGN AND FABRICATION OF 8mm INTEGRATED FLIP-CHIP RING MIXER

用HP ADS软件优化设计了 8mm集成环形倒扣混频器电路 ,在射频频率为 35 .1GHz,本振频率为 35GHz时 ,三端口具有良好的隔离特性 ;计算机仿真最佳本振功率为 6～ 15dBm ,变频损耗小于 5dB .研制了集成倒扣 8mm混频器芯片面积为 3× 3.75 μm2 。

8mm integrated flip-chip ring mixer circuit is designed and simulated with HP-ADS software. The simulated three ports isolation is nicer when RF is 35.1GHz and local frequency is 35GHz. Simulated the best LO power is 6 similar to 15dBm with computer, conversion loss is less than 5dB. 8mm integrated flip-chip ring mixer with chip size 3 x 3.75 mum(2) is fabricated. Measured results are almost consistent with simulated results.
