Abstract
Disclosed herein are systems and methods for reducing intermodulation distortion (IMD) in switches using parallel distorter circuits. A switch circuit can include having a switch arm and a distorter arm that is configured to act as a compensation circuit to compensate for non-linearities in the switch arm. The switch circuit can include a plurality of FETs in the switch arm configured to provide switching functionality. The distorter arm is configured to compensate for a non-linearity effect generated by the FETs of the switch arm when it is in an ON state. The distorter arm is configured to compensate for the non-linearity effect generated by the switch arm independent of the frequency of the signal received by the switch arm. Various configurations of switch arms and distorter arms can be implemented to reduce harmonic distortion as well as intermodulation distortion.
