Abstract :
A fast integral equation formulation is implemented in conjunction with the generalised scattering matrix (GSM) to analyze waveguide-based CPW spatial power combiners. The GSM includes internal ports to account for active MMIC devices with passive circuit elements. The Kummer transformation is applied to accelerate slowly converging double series that occur in evaluating the impedance matrix elements.
