摘要

Direct synthesis technique for coupling matrix of mixed topology filters that contain cross-coupled structures and a series of extracted-pole sections is proposed and demonstrated. Instead of evaluating elements one by one in conventional synthesis, the canonical coupling matrix, including all the cross-coupled and extracted-pole couplings, can be solved altogether one time by using the proposed technique. The direct synthesis is based on a process for the admittance function construction of a filter, yielding a mixed topology prototype where one or more extracted-pole sections are generated at the source port naturally. A sixth-order filter is carried out as an example, which verifies the validity of the proposed technique.
