Do someone give me some suggestions on how to matching the electric impedance for the whole circuit. I use a 20M function generator, and co-axial cable, and a oscilloscope. the transducer is made by myself, I need the characterize its property.

you need know the real and imaginary part of your transducer impedance at the center frequency.
Then you can use simple serial inductor to cancel the imaginary part by using our Ultrasound Calculator.
A more complicated way is L-shape or T shape matching. It is not widely used.
