Apparatus and method for amplifying signal power in a communication system |
摘要 |
A transmitter is provided for amplifying signal power in a communication system. The transmitter includes a single-tone signal generator for generating a single-tone signal; a baseband signal generator for generating a baseband signal; a bias modulator for switching a positive bias signal to a first power amplifier using the baseband signal, and switching a negative bias signal to the second power amplifier using the baseband signal; the first power amplifier for power-amplifying the single-tone signal using the positive bias signal; and the second power amplifier for power-amplifying the single-tone signal using the negative bias signal.
