Abstract: A multiband transceiver (200) including transmit sub-circuits (TSCs) arranged in parallel, a multiplexer (222) receiving RF signals from the TSCs at input ports (290, 292, 294), and a directional coupler (DC). Each TSC (210, 212, 214, 216, 218, 220) is configured to support communications in a respective frequency band. The multiplexer is configured to route signals from the input ports to a common output port (296) and to reduce harmonic distortion induced by the TSCs. DC (226) has an input port (1) connected to the common output port, a transmitted port (4) connected to an antenna port, and a coupled port (3) coupling a portion of the RF signal to a common feedback loop (CFL). The CFL (270) provides a feedback signal coupled to each TSC. Each TSC is responsive to the feedback signal for maintaining a controlled power output at the antenna port over a range of frequencies.

Abstract: A temperature sensing system for a flange mounted device is provided. The temperature sensing system (100) can be comprised of a flexible wiring board (102). The temperature sensing system can be further comprised of a temperature sensing device (122) mounted to the flexible wiring board. The flexible wiring board can have one or more conductive traces (114a, 114b, 114c) disposed thereon. The conductive traces can form an electrical connection with the temperature sensing device. The temperature sensing system can also comprise a thermal pad directly connected to the temperature sensing device. The thermal pad can be formed of a thermal conductor. The thermal pad can also have a thermal contact surface. The thermal contact surface can be sized and shaped for direct physical contact with a portion of the device (302), wherein thermal energy is communicated directly from the thermal pad to the temperature sensing device. A method for sensing a temperature of a flange mounted device is also provided.

Abstract: Transmitter (116) designed to automatically reconfigure one or more circuit parameters associated with an RF power amplifier (210) in response to certain user input commands. Specifically, a transmitter circuit configuration is automatically modified under certain conditions to produce a higher RF output power. The higher RF power output is possible because the transmitter configuration is adjusted specifically for use under a particular set of operating conditions. The operating conditions that trigger the higher powered configuration include burst transmission mode.

Abstract: An RF switch (104) that is activated by the insertion of a connector. The RF switch (104) can comprise one or more antenna adapters that can be formed by a number of predetermined RF connector types. The RF switch can include a switch housing (204). A first, second, and third coaxial RF connectors (201, 202, 203) can be mounted to the switch housing (204). The first, second, and third coaxial RF connectors (201, 202, 203) can individually have both an inner and outer conductor (205-206; 207-208; 209-210, respectively). An actuator (501) can be movable from a first position to a second position responsive to a mechanical force applied to the third coaxial connector (203). A switch element (512) can be responsive to the actuator (501). When in the first position, the switch element (512) can exclusively form a conductive path between the first and second coaxial RF connectors (201, 202).
