ABSTRACT:
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.
