摘要： A band-pass filter device includes a waveguide filter, a first circuit board section, a first antenna, a second circuit board section, and a second antenna. The waveguide filter includes a high-pass portion, a connection portion, and a low-pass portion. The first antenna is disposed on the first circuit board section. The second antenna is disposed on the second circuit board section. A wireless signal generated by the first antenna is transmitted through the high-pass portion, the connection portion, and the low-pass portion of the waveguide filter, and then is received by the second antenna.

摘要： A multiplex filter has at least n filter chambers which are surrounded by a housing and/or at least one insert positioned in the housing. A metal dividing device is constructed in each of the n filter chambers, dividing each filter chamber into m resonator chambers, wherein m≧2. The resonator chambers are coupled perpendicular to the H fields and/or parallel to the central axis or with a component essentially perpendicular to the H fields and/or parallel to the central axis. A common connection is guided into the first filter chamber via a first opening in the housing, and is coupled in the same to the m resonators of the m resonator chambers. As a result of the fact that the coupling is established perpendicular to the H field, the resonator can have a very compact construction.

The enclosure is located on the duplexer; the intermediate RF processing unit is located inside a cavity enclosed by the enclosure and the duplexer, or on the duplexer; a duplexer cavity and a heat dissipation part exist on the surface of the duplexer; the opening of the duplexer cavity is opposite to or against the enclosure; the heat dissipation part is designed to dissipate heat of the intermediate RF processing unit; and the duplexer is integrally molded. The foregoing technical solution requires no external fasteners, reduces the time of production and assembly. In addition, waterproof design and shielding design are not required, and thus improves the reliability.
