<p>PURPOSE: A system and a method for transmitting power calibration of multi channel wireless communication apparatus are provided to simply and promptly necessary gain value according to each channel at a multi channel wireless communication apparatus with a plurality of channels. CONSTITUTION: An RF(Radio Frequency) transceiver(130) comprises a pre-amplifier(132). The pre-amplifier pre-processes a transmission signal transmitted to a plurality of channels by amplifying the gain of the transmission signal. A power amplifier(140) amplifies the electricity of the transmission signal. A calibration controller(20) measures the gain value of the pre amplifier and the output of the power amplifier at each channel by controlling a radio communications controller(110) and performing calibration at a first and second channels.</p> |
