Abstract :
The properties of coplanar transmission lines (CPWs) and -filters on polycrystalline diamond substrates are investigated over the frequency range from 1-120 GHz. Experimental results obtained for different geometries are in good agreement with theoretical predictions. Coplanar transmission line technology was applied to flip-chip diamond substrates for power amplifier MMICs.
