چکیده :

In this paper design procedure and electromagnetic simulation results of an ultra-wideband continuous class J/B power amplifier is reported. With the help of SRFT CAD tools in MATLAB and load/source pull capability of advanced design system (ADS), appropriate output and input matching are synthesized along 0.4-2 GHz band. Then by using of CGH40010F device from Wolfspeed, layout equivalent of designed PA is extracted and the circuit is cosimulated on RO4003c substrate model. ±0.8 dB output power flatness with drain efficiency above 58% across more than 130% fractional bandwidth introduce the designed PA as a good candidate for broadband high efficiency applications.
