英文摘要：

As the bipolar square-wave widely used in various fields, so in practical applications the flexibility of the requirements of its growing. In this paper, MCU, MOSFET and driver IC IR2110 as the main design of a cycle can be adjusted amplitude bipolar square wave transmitter, and the circuit is simple, easy, easy to debug. Then, circuit is simulated and experimented, and a reasonable simulation parameters are selected by the actual experiment and debug circuit, and completed the design of the amplitude, frequency and power of the transmitted signal which validated the circuit＇s stability, reliability, reasonable.
