Modern Approaches to Broadband Matching Problems: Real Frequency Solutions

In practice, computer-aided design (CAD) techniques are employed to solve the broadband matching problems. This chapter first introduces the real frequency line segment technique to handle single matching problems. Then, it discusses real frequency direct computation technique (RFDT) via Bode or Gewertz procedures to solve double matching problems. The chapter examines the design of an actual matching network for a physical monopole antenna manufactured for a special purpose. It then discusses design of a single matching equalizer for the ultrasonic T1350 transducer. The chapter also describes the simplified real frequency technique (SRFT), which is suitable for designing single and multistage microwave amplifiers. Finally, it provides the listings of the amplifier design programs and related functions developed in MATLAB.
