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.
