摘要：
A time division multiple access FDD wireless unit has a first local oscillator 8 for oscillating a first frequency; a second local oscillator 12 for oscillating a second frequency; a n-times multiplier 14 for multiplying the second frequency by n; a m-times multiplier 18 for multiplying the second frequency by m; a converter 6 for transmitting frequency of difference between a reception signal and an output of the first local oscillator 8; a converter 11 for transmitting frequency of sum or difference between an output of the converter 6 and an output of the n-times multiplier 14; modulator 19 for modulating an output of the m-times multiplier 18; a converter 22 for transmitting frequency of sum of an output of the modulator 19 and the output of m-times multiplier 18.
