Circuit and Method for Transmitting or Receiving Signal

摘要

A circuit, including a receiving path, for converting a first analog radio frequency (RF) input signal to a digital intermediate frequency (IF) input signal, wherein the first analog RF input signal includes a first signal component conforming to a first wireless transmission standard and a second signal component conforming to a second wireless transmission standard; a first digital down converter, for receiving and processing the digital IF input signal to generate a first digital baseband signal corresponding to the first signal component; a second digital down converter, for receiving and processing the digital IF input signal in order to generate a second digital baseband signal corresponding to the second signal component; a first baseband processing module, for processing the first digital baseband signal according to the first wireless transmission standard; and a second baseband processing module, for processing the second digital baseband signal according to the second wireless transmission standard.
