Design of broadband microwave amplifiers with mixed-elements via reflectance data modeling
A practical method is introduced to design single-stage broadband microwave amplifiers with mixed lumped and distributed elements via modeling the reflectance data obtained from lumped-element input and output matching network prototypes. The same transducer power gain level is obtained by using less number of lumped-elements in the mixed-element amplifier than that of the lumped-element amplifier prototype. A mixed-element amplifier design is presented to exhibit the utilization of the method. It is expected that the method will be employed to design microwave amplifiers for broadband communication systems. (C) 2007 Elsevier GmbH. All rights reserved.
