    摘要: A satellite communication system (SCS)(100) and method (300) are provided that provide a geographically co-located user assignment system. For unit-to-unit communication, each group of subscriber units is instructed to operate in a half-duplex unit to unit mode. The geographically co-located user assignment system comprises an assignment unit (201), a storage unit (203), and an instruction unit (205) such that a first subscriber unit (204) initiates unit to unit communication with at least a second subscriber unit (206, . . . ) in the first subscriber unit's user group utilizing a multiple access channel assigned to that group by transmitting on an assigned satellite downlink frequency of the multiple-access channel on a push-to-talk basis.

    摘要: A laminated low-profile dual filter module for telecommunications devices and method provides both Groupe Spécial Mobile (GSM) and Digital Cellular System (DCS) transmit filters in a small package. The filter module comprises multiple layers of ceramic substrate with metal circuit patterns sandwiched between. Two separate filters are implemented within the layers, with a first filter comprising a first set of layers and the second filter adjoining within a second set of layers. Resonators for each filter are positioned at the opposite sides of the module, in order to avoid coupling between the resonators and ground layers are interspersed for isolation. Capacitors are implemented by a first plate defined by an area on one metal layer with the adjacent layers providing ground planes that form the second plate.

    摘要: A power amplifier (517) for amplifying an operating signal includes an amplifier (538), an amplifier (540), and a power combiner (518) with harmonic selectivity. The power combiner (518) includes a transmission line section (541), a transmission line section (545), and a resistor (554). The transmission line section (541) is coupled to an amplifier output of the amplifier (538), and the transmission line section (545) is coupled to an amplifier output of the amplifier (540) and to the transmission line section (541). A capacitor (546) is coupled in parallel to a transmission line section (542) of the transmission line section (541), and a capacitor (548) is coupled in parallel to a transmission line section (544) of the transmission line section (545).

    摘要: A planar microstrip inductor formed from a spiral shaped conductive path of material on a dielectric uses a bifilar spiral by which both the connection nodes of the inductor can be brought out to the edge of the substrate. The bifilar winding by which both connection nodes are available from the exterior of the spiral shape includes the use of a jumper wire to connect the inner node of the inductor to a circuit.
