- Provided is a mode transition circuit for transferring a RF signal and a transceiver module having the same. The mode transition circuit includes: a planar transmission line mounted at a RF substrate for receiving a RF signal from a RF signal generating unit; a via formed inside the RF substrate and connected to one side of the planar transmission line for receiving the RF signal from the planar transmission line; at least one of metal patches formed inside the RF substrate and connected to the one side of the via for receiving the RF signal from the via; and a hole formed inside a low frequency substrate and connected to one side of the metal patch for receiving the RF signal from the metal patch.
