1. A CMOS antenna switch, comprising:

  • an antenna operative at a plurality of radio frequency (RF) bands;

    a transmit switch in communication with the antenna; and

    a receiver switch in communication with the antenna, wherein the receiver switch includes a plurality of transistors, including a first transistor and a second transistor, wherein the first transistor includes a first source, a first drain, and a first body substrate, wherein the second transistor includes a second source, a second drain, and a second body substrate, wherein the first body substrate is electrically connected to the first source or the first drain, and wherein the second body substrate is selectively connectable between a resistance and ground.
