DOUBLE FREQUENCY COMBINER

摘要

A double frequency combiner includes a first coaxial resonator band pass filter (610, 611) and a second coaxial resonator band pass filter (620, 621) which set in a box. The box includes a case (6), a strap (2) and a cover (4). On the case (6) there are the first coaxial resonator band pass filter (610, 611) and the second coaxial resonator band pass filter (620, 621) which are separated by a metal sheet. A combination port (Port1), a first port (Port2) and a second port (Port3) are set on the side of the case (6). Each blocking capacitor is set in the coaxial cavity (610, 620) of those two coaxial resonator band pass filters. The strap (2) is fixedon the case (6). The first and second direct-current channel are set on the strap(2). Therein,each low-pass filter in the first and second direct-current channel is fixed on the edge of the upper surface of the coaxial cavity (610, 620) with support members. The cover (4) is locked with the case (6). The blocking capacitors are parameter distributed capacitors.
