Abstract :
In this paper a reconfigurable input matching network (IMN) for power amplifiers (PA) is designed and simulated. An IMN is realized as T-section, where reconfigurability is achieved by switch element (PIN diode switch). When PIN diode switch is ON the PA operates at 3.45 GHz. In PIN diode switch OFF state the PA operates at 3.75 GHz. The S-parameters and power added efficiency (PAE), of about 45% and 50% at 3.45 GHz and 3.75 GHz respectively, are presented.
