Abstract

An improved approach to the computer-aided modelling of impedance-transforming microstrip-balanced stripline tapers used in microwave doubly balanced mixers is presented. The spectral domain method has been used to determine the parameters of a suspended microstrip with finite ground plane width. Calculations show that dispersion effects in the analysed structure are insignificant. The designed and realised 50–100ω transition on a 1.5mm thick alumina substrate exhibited very good or acceptable performance up to 10 and 15GHz, respectively. A method to suppress undesired modes appearing in the case of shielded transitions has been proposed and experimentally verified.
