Tunable circuit elements for dynamic, per element power

Abstract

A communication device and method mitigates specific absorption rate (SAR) exposure of a user. A radio frequency (RF) transmitter amplifies outgoing communication signals to a total radiated power (TRP) level. A matching network electrically connected to the RF transmitter receives the outgoing communication signals. The matching network divides the TRP level of received, outgoing communication signals to a first power level at a first network output and to a second power level at a second network output. First and second antennas electrically connected respectively to the first and second network output radiate the divided, outgoing communication signals at the first and second power levels. A SAR controller communicatively connected to the matching network controls the matching network to shift transmit power between the first and second antennas while maintaining TRP level to reduce SAR exposure of the user.
