US 6,609,010 B1 · Dual frequency band transceiver

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.

A dual frequency band transceiver adapted to be operated in two different transmission frequency bands, comprising

a 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.
