Abstract

See full text

An amplifying apparatus is provided. The amplifying apparatus comprises an amplifying circuit comprising a power amplifier and a bias circuit, the bias circuit is configured to detect an ambient temperature of the power amplifier to output a temperature voltage and regulate an internal current based on an input control signal to supply a bias current obtained by the regulation to the power amplifier; and a temperature control circuit that generates the control signal based on the temperature voltage during initial driving from a transmission mode starting point in time to an input point in time at which an input signal is input and outputting the control signal to the amplifying circuit.
