Design of SAW amplifier with distributed semiconductor transistor
In this paper, we present the design of a novel SAW amplifier that consists of multi-stripe tapping electrodes and a GaAs FET amplifier. Using a general circuit simulator, we analyse the frequency characteristics of the SAW amplifier. The SAW amplifier with differential operation shows wideband frequency characteristics better than that without differential operation. We also investigate the frequency characteristics by changing tapping electrode pitches and the impedance matching condition between SAW and FET. These results confirm that the SAW amplifier is applicable to wideband communication systems and signal processing systems.
