Recent trends in sonar design have mostly required increasing power output of sonar transducer in the 'acoustics. This paper presents the power amplifier and the band pass filter for sonar system which includes sonar transducers and matching network In order to prove the validity, simulation is carried out using Pspice and Matlab.<br/>
Instead of using the linear amplifier method which have several the disadvantages in driving transducer, the phase control method is applied to the power amplifier. The band pass filter is required to reduce the harmonics (ie 3rd, 5th. 7th) for the phase control method.
