Abstract
In this paper, a broadband 100-700 MHz power amplifier was designed. The results of simulation are compared with the measurements,The shunt feedback of power amplifier module provides the linear and broadband frequency amplification. The push-pull topology with ferrite balun provides enhanced efficiency and high power generation along In this work a commercially available LDMOS transistor (D2003UK) is used, The amplifier can deliver 6W to a 50 ohm load and has 14dB gain.Broadband high power amplifiers are considered as key components in next generation software defined radio communication systems. In principle, application of a linear, highly efficient wide band amplifier can replace several narrow band power amplifiers, yielding reduced costs and form factor, This paper uses D2003UK a transistor to achieve a 6 Watt amplifier for broad band .
