    摘要: An antenna assembly (10) includes a ground plane formed on a chassis (12) of the radio and the functional knob forming an antenna element (11). The antenna assembly further includes a slot or notch element (14) in the ground plane substantially adjacent to the functional knob and having a length less than ¼ wavelength, and a coaxial cable (13) feeding the antenna element. A shield of the coaxial cable can be directly connected to the ground plane and a center conductor of the coaxial cable can be directly coupled to the functional knob to provide a galvanic connection for narrowband performance or the center conductor can be electromagnetically coupled to the functional knob for wideband performance or both. The antenna assembly can create a zero volume notch type ground excitation.

    摘要: A linear RF transmitter (100) includes a forward path including a baseband signal combiner (109) and an RF (radio frequency) power amplifier (123), and a linearizing control loop from an output (127) of the RF power amplifier to an input of the combiner (109). A feedback control path (105, 107) of the loop delivers a baseband error control signal to the combiner. The transmitter further includes a test signal generator (102) to apply to the combiner in a closed loop level training mode a test signal comprising a voltage Vin which increases with time in a non-linear manner approaching an asymptotic limit such that in response an output signal produced by the combiner is a voltage Ve which is substantially constant over a period of time.

    摘要: A wireless communication unit (300) comprises a linearized transmitter (325, 500) having a power amplifier (324), a forward path and a feedback path for feeding back a portion of a signal to be transmitted, wherein the feedback path and forward path form two loops in quadrature. A processor (322) applies one or more training signals to a first quadrature circuit loop and a second quadrature circuit loop and measures a quadrature imbalance between the first and second quadrature circuit loops. In response the processor adjusts at least one parameter setting of a loop adjustment function (442) to balance the quadrature circuit loops. A linearized transmitter integrated circuit and method of training are also described. The measuring and compensating for any loop imbalance between digital ‘I’ and ‘Q’ paths around a feedback path provides improved accuracy and stability in phase and/or amplitude.
