摘要：
The paper makes use of the wideband design technique and linear bias circuit to design a dual band power amplifier(PA) for TD- SCDMA. The PA is taped out in the 2um InGaP/ GaAs HBT process and verified in the evaluation board by the QPSK modulated stimulus with a chip rate of 1.28Mcps in 2.0 GHz. The measured result shows that the power gain, linear output power and power added efficiency are respectively 27dB, 28dBm and 39% with the adjacent channel power ratio of -33.08dBc in offset +/- 1.6MHz.
