Abstract
A transceiver device includes a transmitter circuit and a receiver circuit. The transmitter circuit is configured to couple an antenna and includes a first mixer and a first buffer circuit. The first mixer is configured to output a first radio frequency signal according to a first baseband signal and a first local oscillator signal. The first buffer circuit is configured to output the first local oscillator signal to the first mixer and includes a plurality of first buffers. The receiver circuit is configured to couple the antenna. A first buffers-coupled-in-parallel quantity of the first buffer circuit is adjusted according to an operation condition.
