We present an analytical charge conservative large signal model for MODFETs, which is valid up to MM-wave frequencies. Although the model equations are simple, an excellent accuracy in the representation of the nonlinear elements of the FET is achiev

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 theore

By using a coplanar layout, incorporating transmission lines loaded with lumped shunt MIM-capacitors, the size of millimeter-wave power amplifiers can be considerably reduced. This is demonstrated by the design of two compact GaAs PHEMT power amplifi
