In this talk, regarding to the design of compact filter, one kind of design method based on composite right- and left-handed (CRLH) structures is proposed. Aiming at different desired performances, this method initially starts from equivalent circuit and results in corresponding lumped elements, which are eventually transformed to structural parameters of the desired filters with different performance...
This paper proposes a novel design methodology for dual-band Doherty power amplifier (DPA) with improved dual-band combiner. The presented design method simplifies and optimizes structure of dual-band DPA. According to the theoretical analysis and measurement verification, the DPA with improved combiner can provide a high efficiency at both low and high input power levels at two working frequency...
