ABSTRACT:
A single-block ceramic filter (100) providing both pass and stop bands couples an RF signal from transmitter (180) to an antenna (190) and an RF signal from the antenna (190) to a receiver (170). The ceramic filter (100) includes seven holes (102, 104, 106, 108, 110, 112 and 114) each having an elongated cross section and being surrounded by capacitive strips (e.g. 130, 131, 140 and 141 for hole 106), and electrodes (120, 122 and 124) coupled to receiver (170), transmitter (180) and antenna (190), respectively. A bracket (150) may be soldered to the ceramic filter (100) for holding cables coupled to the receiver, transmitter and antenna and for mounting the ceramic filter in a radio transceiver.
