摘要
In this paper, a reconfigurable input matching network (IMN) is used to obtain reconfigurable RF power amplifier (RPA). An Input Matching Network is realized as simple T-section, where reconfigurability is achieved by switch in shunt transmission line. An optical switch (OS) and a PIN diode are used separately, and results are presented for both cases. When an OS or a PIN diode switch is ON, RPA operates at 1.9 GHz, otherwise RPA operates at 2.2 GHz. An Output Matching Network (OMN) is realized as wideband circuit. A Cree's CGH21240 AWR Microwave Office (MWO) model of wideband transistor is used for RPAs. The S-parameters and power added efficiency (PAE) of about 50% and 35% at 1.9 GHz and 2.2 GHz, respectively, for both types of RPAs are presented.
