Abstract(in English) | A feedforward power amplifier (FFPA) with a series diode linearizer using a bias feed resistance is presented. To improve overall FFPA efficiency, a series diode linearizer is used to provide main amplifier linearization. FFPA efficuency optimization design considering FET effeciency and gain trade-off have been demonstrated. From measured overall performances of the FFPA, the efficiency enhancement of the series diode linearizer was shown. The developed FFPA achieved the high efficiency and output power of 10% and 45.6dBm at 10MHz offset ACLR-50dBc under W-CDMA 2 carriers signal. |
