Linear power amplifier with a modified predistortion compensation for NCDMA applications
The selection of the matched transistor pair in a cascaded architecture for predistortion compensation is nontrivial. In this study, a modified architecture of predistortion with two paths is presented for the high power amplifier. The goal is to develop a 10W linear power amplifier with LDMOS transistor for 8 channels NCDMA repeater from 870 to 880MHz. With the modified scheme, the improvement of intermodulation is larger than 10dB and spurious is less than 50dBc.
