Abstract
A radio receiving apparatus has a receiving section for receiving a radio signal, a local oscillating section for generating a first local oscillation signal and a second local oscillation signal, wherein the first local oscillation signal and the second local oscillation signal have each of a first frequency and a second frequency differing from a received frequency. The apparatus also has a frequency converting section for mixing the received signal output from the receiving section and the first local oscillation signal to output an intermediate frequency signal and an orthogonal converting section for orthogonal converting the intermediate frequency signal output with the second local oscillation signal.
