    摘要: According to one exemplary embodiment, a switching device with phase selection terminals to select between at least two phase shifting modes to reduce intermodulation distortion in the switching device includes a first phase selection terminal to select a first phase shifting mode of the switching device by enabling a first phase shifter in a first phase shifting switching branch coupled to an input of the switching device. The switching device further includes a second phase selection terminal to select a second phase shifting mode of the switching device by enabling a second phase shifting switching branch coupled to the switching device input. The intermodulation distortion in the switching device is reduced by selecting one of the first and second phase shifting modes. The switching device may further include a number of FETs coupled in series between an output of the switching device and the first and second phase shifting switching branches.

    摘要: Systems and methods for controlling output power from a power amplifier include a power amplifier configured to generate a power output signal. An output matching circuit is in communication with the power amplifier and is configured to provide an impedance match between the power amplifier and the load. The output matching circuit includes a coupler circuit configured to detect the level of the power output signal. The coupler circuit is further configured to generate a coupler circuit output signal that is proportional to the detected output power level. A feedback control loop circuit is in communication with the coupler circuit and the power amplifier. The feedback control loop circuit is configured to control the power output level based at least in part on the coupler circuit output signal.
