1. A radio frequency (RF) switch branch having a reduced nonlinearity, said RF switch branch comprising:

  • a primary transistor;

    a first transistor having power terminals electrically connected between a drain node and a body node of said primary transistor;

    a second transistor having power terminals electrically connected between said body node and a source node of said primary transistor;

    wherein one of said power terminals of said first transistor and one of said power terminals of said second transistor are coupled to ground through a body resistor of said primary transistor;

    wherein a ratio between a body node-to-ground impedance of said primary transistor and either a drain-to-body impedance of said primary transistor or a source-to-body impedance of said primary transistor increases without increasing said body node-to-ground impedance when said primary transistor is ON.
