Özet

© 2022 IEEE.In this paper, Carlin's Real Frequency Line segment technique (RF -LST) is generalized to cover both single and double matching problems. The new method is called the 'Unified Real Frequency-Line Segment Solutions to Broadband Matching Problems (U-RFT)'. U-RFT is an excellent numerical tool to assess the gain-bandwidth limitation for the given complex terminations of the matching problem. An example is presented to exhibit the utilization of the newly proposed U-RFT method to design a two-stage power amplifier using the Wolfspeed GaN transistors of CMPA0530002S and CG2H40035 which yields 35 Watts output power with 78% efficiency.
