本文介绍了77 GHz共面波导（CPW）单片毫米波集成电路（M/sup 3/IC） BPSK矢量调制器的结果，据我们所知，这是基于InP技术的基于CPW的w波段直接载波频率调制器的首次演示。该电路采用平衡反射拓扑，采用0.12 /spl mu/m InP晶格匹配HEMT m /sup 3/IC工艺实现。该电路的通断隔离度大于25 dB，其开状态之间的相移度为180度。
This paper presents results of a 77 GHz Coplanar Waveguide (CPW) Monolithic MilliMetre-wave Integrated Circuit (M/sup 3/IC) BPSK vector modulator which is, to our knowledge the first demonstration of a CPW-based W-band direct carrier frequency modulator on InP technology. The circuit, which employs a balanced reflection topology, was realised using a 0.12 /spl mu/m InP lattice matched HEMT M/sup 3/IC process. The circuit demonstrates an on-off isolation of greater than 25 dB and 180 degrees of phase shift between its ON states.
