The design and modeling of an ultrasonic 1-3-composite transducer is presented. We describe a successive identification method of the complete transducer, consisting of a front protection layer, a backing and an electrical matching network. Furthermore we discuss the influence of the internal impedance of the electrical source driving the transducer. The aim of this contribution is to provide a complete identified transducer model, to characterize influences of the assembling process to the electro-mechanical behavior and finally to design a high bandwidth composite transducer.
