Abstract: A cable-free programmable radio is described. In one exemplary implementation, a radio includes an infrared port configured to receive programmable information from a host device via an infrared signal. The radio also includes a control system having a selectable programmable mode to enable the radio to download the programmable information from the host device and configure the radio function in accordance with the programmable information. A radio may be configured/reconfigured (such as when 'cloning' the radio) by connecting the radio to a host device through the infrared port, wirelessly.

Abstract: A distributed Internet Protocol (IP) voting system and method for use in Land Mobile Radio (LMR) Systems having a central send-and-receive site (12) and one or more receive-only sites (26). In the distributed voting system, receive-only sites (26) are directly linked to a control point (41) using a network (40) and associated packet transmission protocol. This may be a high-speed asynchronous data link such as a standard IP network link. Each remote site (26) receiving digital data, calculates a bit error for that data. This error calculation is incorporated into the data header information. The data header information and data are placed in an IP packet and transmitted as a User Data Protocol (UDP) message to the control point. The control point (41) selects the lowest bit rate data message, or the first control message, and retransmits it using a standard radio air interface protocol, such as the APCO Project 25 air interface protocol.

Abstract: The invention comprises a technique and associated mechanisms by which dielectric resonator circuits, such as filters, can be tuned in both frequency, bandwidth or both without the need for irises, tuning screws and/or tuning plates. In accordance with the invention, the positions of the dielectric resonators (401) are adjustable relative to each other within a cavity in multiple ways, including vertically and horizontally. The dielectric resonators (401) also may tilt relative to each other. Furthermore, an off-center longitudinal hole can be machined in one or more of the dielectric resonators (401) so as to make the electromagnetic field of the resonator non-uniform so that the dielectric resonator can be rotated about its longitudinal axis to alter the coupling between dielectric resonators. In accordance with another aspect of the invention, frequency tuning can be accomplished by using two separate dielectric resonators (401) adjacent each other, one on top of the other, and adjusting the vertical spacing therebetween to achieve the desired center frequency within that dielectric resonator pair.

Abstract: [0035] A high-speed cross-point switch is built on a preferably silicon substrate and uses bipolar transistor switching elements. Preferably, the bipolar transistors are SiGe bipolar junction transistors. Intersecting conductive input and output microstrips are preferably thinned at their intersections to reduce shunt capacitance between the coupled lines. It is also preferred that the input buffer be connected in cascode fashion with the switching transistors in order to create an amplification stage. The signal and its inverse are carried on balanced microstrip pairs in order to reduce electromagnetic field strength at the center of the balanced line pairs thereby improving isolation between two crossing balancing pairs.

Abstract: A transceiver and transmitter are shown. A baseband processor receives a signal for transmission. It converts the signal into amplitude and phase polar components. Each component is then processed - the phase component through a wideband phase modulator and the amplitude component through a wideband amplitude modulator, and the components are then recombined for further processing or transmission.
