Abstract
There is provided a baseband structure of a transceiver. In an embodiment, a baseband structure of a transceiver includes a Variable Gain Amplifier (VGA) configured to amplify an input signal by controlling a gain, one or more Fixed Gain Amplifiers (FGAs) connected in series to the VGA and configured to amplify an output signal of the VGA, and one or more selection switches configured to selectively operate the FGAs. In accordance with the present invention, since a plurality of FGAs is selectively driven according to a necessary gain and an LPFG includes an FGA, power consumption and the size of a chip can be reduced and the overall performance of a transceiver can be improved.
