ABSTRACT:
A surface mount dielectric block filter with an integral transmission line connection to external circuitry is disclosed. In order to connect an input/output capacitor metallized on the surface of the dielectric block to a substrate upon which the dielectric block is directly mounted, a transmission line of appropriate characteristic impedance disposed on the surface of the dielectric block is connected between one plate of the metallized capacitor and an input/output terminal. Two such dielectric block filters may be coupled together to form a radio transceiver duplexer.
