  Abstract

In the thesis, we propose a new type of the predistortion linearizer using frequency multiplier. The linearizer utilizing the 2nd and 3th harmonic used the individual control of the 3rd and 5th order intermodulation distortion(IMD) component. This structure is composed of wilkinson power combiner for combine and isolation of output signal, 3rd order IMD product controller using doubler and 5th order IMD product controller using tripler. The proposed predistortion linearizer controlled by individual order is obtained for about -16dBc and 18dBc of 3rd order and 5th order IMD components, respectively, over the frequency band 870MHz to 880MHz at the output power of 34dBm/tone.
