Abstract:
A dual frequency band transceiver adapted to be operated in two different transmission frequency bands, comprisinga control unit (8) controlling a switch (6) for changing between a first transmission frequency band (fC1) and a second transmission frequency band (fC2), wherein the control unit (8) is adapted to change between a first and a second channel bandwidth correspondingly to the switching between the first transmission frequency band (fC1) and the second transmission frequency band (fC2) and wherein the first and the second channel bandwidth satisfy the following equation: n*Bc1=m*Bc2, in which Bc1 and Bc2 respectively represent the first and the second channel bandwidth, and n and m are integers starting with 1 which satisfy the equation n/m=2i in which i is a positive or negative integer.
