POWER AMPLIFIER WITH LINEARIZED GAIN

摘要

PURPOSE: A power amplifier with a linearized gain is provided to vary the reference voltage of the power amplifier by utilizing the reference voltage of the power amplifier using the power detection voltage having the feedback power detection function. CONSTITUTION: A power amplifier with a linearized gain includes a power amplifier(12) and a feedback input unit(11). The power amplifier(12) amplifies the power with having a constant gain for the input in response to the reference voltage. After the output of the power amplifier(12) is received and the received output of the power amplifier(12) is converted into the voltage, the feedback input unit(11) transmits the amplified output of the power amplifier(12) so as to be used as a reference voltage of the power amplifier(12).
