Abstract

High power amplifier based on the Wilkinson energy has been constructed and fabricated in this study. The 45-50W primary speaker unit is manufactured using horizontally distributed metal oxide semiconductor (LDMOS) materials and ferromagnetic materials. Field Effect Transistor (FET) Transistor PTFA260451E. Wilkinson Energy Complex has employed to merge dual entered energies to achieve 90 watts of power. The suggested power amplifier was investigated, planned and advanced utilizig (MATLAB) software traditional Wilkinson power dividers (WPDs) might produce acceptable response near to suggested center frequency Anyhow, such WPDs might further displayed low out of range response whereas it needs adding significant procedures. In favor of enhancing the preset performance state, a modification has been made Proposed utilizig microstrip WPD which shows significantly improved stopping range with large separation. A low-pass filter (LPF) model is employed in each sections of the harmonic damping splitter to save power. The suggested structure is constructed using microelectromechanical system oscillators (MEMS) against the film's sonic resonator (FBAR) with a center frequency of 2.65-3 GHz with two sections and 50 Ohm impedance for 90 watts amplification power.
