Abstract
A system and method are disclosed for controlling transmit power amplification in a wireless transmitting device. A processor receives data to determine whether a communication channel from a transmitting device to a receiving device is strong enough to support a target data transmit rate of the devices with a power amplifier either on or off. The processor controls a switching device between a data transmitter circuit and the transmitter's antenna based on the quality of the communication channel. In a first state, the switching device connects the data transmitter circuit to the power amplifier to increase the strength of the signal communicated to the antenna. In a second state, the switching device bypasses the power amplifier. The power amplifier is turned off when the switch is in the second state, thereby decreasing the power consumed by the transmitting device as it transmits data at the target data transmit rate.
