A ceramic block filter (100) includes coupling pins (101 and 102) disposed in holes (124 and 125) in corresponding electrodes (121 and 122) for interconnecting the filter to radio frequency devices, such as a radio transceiver. During manufacture of the filter (100), the coupling pins (101 and 102) are bonded to conductive material (131) of the holes (124 and 125) and corresponding electrodes (121 and 122) when the rest of the conductive material (160) is fired. To facilitate the electrical bond during the manufacturing process, the coupling pins (101 and 102) may be silver or silver plated and co-fired at the same time. Since the coupling pins (101 and 102) are fired at the same time as the rest of the conductive material, a reliable and inexpensive bond is achieved between the coupling pins (101 and 102) and the conductive material of the holes (124 and 125) and corresponding electrodes ( 121 and 122).
