Patent ID: 7248845

Claim:
A transmitter for communicating information, the transmitter comprising: a power amplifier configured to receive a source signal and generate an amplified output signal; an antenna coupled to the power amplifier, the antenna configured to radiate the amplified output signal; a variable-loss filter coupled between the power amplifier and the antenna; and a controller coupled to the power amplifier and the variable loss filter, the controller configured to control a gain of the power amplifier responsive to a power level of operation of the transmitter to a establish first gain of the power amplifier during a low power operation of the transmitter and a second gain during a high power operation of the transmitter, the first gain being less than the second gain, the controller further configured to control an attenuation of the variable-loss filter to establish a first signal attenuation level during the low power operation of the transmitter and a second signal attenuation level during the high power operation of the transmitter, the first signal attenuation level being greater than the second signal attenuation level.
