Abstract

A dual frequency band transceiver (10) is provided adapted to be operated into different transmission frequency bands. A control unit (8) controls a switching (6) between a first transmission frequency band FC1 and a second transmission frequency band FC2, wherein the control unit (8) changes correspondingly and simultaneously to the switching (6) in the first transmission frequency band FC1 and the second transmission frequency band FC2 between a first and a second channel bandwidth.The first and the second channel bandwidth satisfies the following equation:n*BC1=m*BC2,wherein BC1 and BC2 are the first and the second channel bandwidth, respectively, and n and m are an integer values starting with 1.
