CAD and electrical performance of new compact power divider suitable for use in M(H)MICs

This paper presents a class of new compact power dividers suitable for use in microwave and millimeter-wave integrated circuits (ICs). Compared to the classical structure, the new topology of the power divider is made with a sinusoidally taped circuit shape attached with multiple output ports that are co-linearly located along one plane. The phase and magnitude balance of a signal for the output ports are achieved with diffractive hole(s) etched in the middle of the circuit contour. An efficient field-theoretical CAD procedure is applied to accurate design of this irregularly shaped circuit with a mixed waveguide model and boundary integral method. Electrical performance of the power divider shows a good agreement with theoretical prediction.
