ABSTRACT:
A differential signal is coupled to an unbalanced port (116) from a balanced port (110) by receiving a first portion of a first phase of a differential signal at a first resonator (104) and receiving a second phase of the differential signal at a second resonator (108). The first portion of the first phase of the differential signal is coupled to a first matching element (112) and the second phase of the differential signal is coupled to a second matching element (118). The first portion of the first phase of the differential signal is coupled to a phasing element (122) through the first matching element (112) and a second portion of the first phase of the differential signal, which is a 180 degree out of representation of the second phase of the differential signal, is coupled to the phasing element (122) through the second matching element (118). The first portion of the first phase of the differential signal and the second portion of the first phase of the differential signal are combined in the phasing element (122) to produce an unbalanced signal at the unbalanced port (116).
