<p>A surface mount dielectric block filter (100 in Figure 4A) with an integral transmission line connection (403, 407) to external circuity is disclosed. In order to connect an input/output capacitor (113, 115) metallized on the surface of the dielectric block to a substrate (601) upon which the dielectric block is directly mounted, a transmission line (401, 405) of appropriate characteristic impedance disposed on the surface of the dielectric block is connected between one plate of the metallized capacitor (113, 115) and an input/output terminal (403, 407). Two such dielectric block filters (100 in Figure 8) may be coupled together to form a radio transceiver duplexer.</p> |
