- 論文の詳細を見る
An L-Band high efficiency and low distortion multi-stage amplifier using self phase distortion compensation technique is presented. In this amplifier, the bias condition of the driver-stage transistor is tuned to compensate the phase distortion of the power-stage transistor, and the load and source impedances of the driver-stage and power-stage transistors are optimized to achieve the maximum efficiency with a specified adjacent channel leakage power (ACP) for multi-stage amplifier. The developed amplifier achieves a power added efficiency (E_add) of 42.8% and an output power (P_out) of 26.8 dBm with an ACP of -38 dBc at 1.95 GHz for wide-band code-division multiple-access (W-CDMA) cellular phones.
