Abstract: A wireless communication device (20) provides a matching state between a radio circuit (28) and an antenna assembly (26) in both its retracted and extended positions, and does so with an elegant design that increases reliability and manufacturability by reducing the number and complexity of components and moving mechanical parts. A matching circuit (30), which is reconfigured according to a switch (32) that is responsive to the antenna's position, provides the matching states.

Abstract: A WIRELESS COMMUNICATION DEVICE (20) PROVIDES A MATCHING STATE BETWEEN A RADIO CIRCUIT (28) AND AN ANTENNA ASSEMBLY (26) IN BOTH ITS RETRACTED AND EXTENDED POSITIONS, AND DOES SO WITH AN ELEGANT DESIGN THAT INCREASES RELIABILITY AND MANUFACTURABILITY BY REDUCING THE NUMBER AND COMPLEXITY OF COMPONENTS AND MOVING MECHANICAL PARTS. A MATCHING CIRCUIT (30), WHICH IS RECONFIGURED ACCORDING TO A SWITCH (32) THAT IS RESPONSIVE TO THE ANTENNA''S POSITION, PROVIDES THE MATCHING STATES.

Abstract: A retractable antenna assembly (206; 900) provides a substantially matched antenna impedance to a matching circuit (712) of a radiotelephone (200) whether the retractable antenna assembly is in the extended position or the retracted position. In one embodiment parts (304,312) of a capacitor (714) are integrally formed on an upper portion of the retractable antenna assembly (206) such that when in the retracted position the capacitor (714) contributes to the overall antenna impedance. In another embodiment a capacitor (1302) is integrally formed on the lower portion of the retractable antenna assembly (900).

Abstract: SURFACE-MOUNT FILTER A filter assembly (100) includes a ceramic block filter (102) and shielding bracket (132) which surface mounts to a printed circuit board (152) for interconnecting to radio frequency devices, such as a radio transceiver. The bracket (132) is soldered to the filter (102) and includes two openings (136 and 137) for exposing input/output electrodes (106 and 107) of the filter. The printed circuit board (152) includes an opening (162) shaped to accept the filter (102) and bracket (132) when inserted therein. Transmission lines (156 and 157) are disposed on tabs (158 and 159) and are reflow soldered to the corresponding electrodes (106 and 107) of the filter. The bracket (132) includes two tabs (134) which are reflow soldered to grounded portions of the circuitry on the top side of the printed circuit board (152).
