Abstract As one of the main properties of miniaturized HTSC filters, the complex couplings of HTSC filter is proposed, and the analysis method of these complex couplings is studied. As the method, full wave technology is used to design the filter, and the couplings between or in resonators are studied by this method, then the effects to filtering response of these couplings are discussed. From the aspect of structures, the miniaturization procedure of HTSC filter is under discussion with the complex couplings. There are some miniaturized structures and their simulated and tested results, and the fabricated filters are used in one real communication receiver.
