Abstract:
A mobile communication device (100) of the embodiments will have a transmit diversity antenna system (613) that will comprise at least two antennas and processor/s (607) that will run a transmit diversity control module (609) for controlling transmit diversity output power. Using a power curve, the mobile communication device (100) determines whether a threshold, corresponding to an SAR value, is or may be exceeded. If the SAR threshold is not exceeded given various determined environmental conditions, the mobile communication device (100) continues transmit diversity operation. However, if SAR is about to be exceeded, or is exceeded, the mobile communication device (100) will take action and either reduce overall power, reduce power to one of the transmit diversity antennas, or deactivate one of the transmit diversity antennas in order to bring the SAR level back below the threshold.

Abstract:
An amplifier system to increase the efficiency of amplification systems that employ linear modulation schemes. The amplifier system has a signal amplifier for receiving a constant amplitude input signal and producing an amplified version of the input signal. A variable impedance network presents various impedances to an output of the signal amplifier responsive to a load control signal. An envelope mapping circuit coupled to the variable impedance network produces the load control signal responsive to a desired amplitude modulation (AM) envelope. The various impedances causes the desired AM envelope to be impressed upon the amplified version of the input signal.

A load envelope following (LEF) amplifier system to increase the efficiency of amplification systems that employ linear modulation schemes. The LEF system has a signal amplifier for receiving an input signal that has an amplitude modulation (AM) envelope. The signal amplifier produces an amplified version of the input signal. A variable impedance network is coupled to an output of the signal amplifier and substantially continuously presents various impedances to the output of the signal amplifier in response to a load control signal. An envelope mapping circuit is coupled to the variable impedance network to produce the load control signal in response to and indicative of the substantially continuously varying amplitude of the AM envelope of the input signal.
