| Abstract: | Methods electrically exciting an ultrasonic trandcer are discussed. Three kinds of commonly used high-frequency exciting methods are analysed for their merits and limitations. The chosen MARX circuit based on avanlanche mode gives an efficient unipolar pulse with satisying result(amplitude greate than 400 V with rise time less than 5 ns) on a 100 MHz ultrasonic trandsducer. |

| Keywords: | Unipolar pulse High-frequency ultrasonic transducer Aralanche tube circuit |
