摘要： Provided are a first filter 63a and a second filter 63b each having a pass band in the range of a frequency band that is obtained by, for example, substantially bisecting a frequency band of f1 to f4. In that case, the regions of the first filter 63a and the second filter 63b partially overlap with each other with the center frequency f5 interposed therebetween. In practice, even if the division is not bisection, a configuration is adopted in which a frequency region of the wider band (the first frequency band 61a) closer to a second frequency band 61b side is covered by the second filter 63b. Accordingly, it is possible to suppress the influence of load fluctuation in a multiband-compatible radio communication device.

摘要： There is provided a solution for dual channel transmission in a radio communication device. Both transmission signals to be transmitted on different channels are mixed two times by using oscillator signals having the same frequencies for both transmission signals, and the transmission circuitry is arranged to process the signals so that the transmission signals are nevertheless up-converted to different frequency channels.
