The transmitting transducer is the core component of the acoustic logging while drilling tool (ALWD). Its working bandwidth and the strength of the radiated acoustic energy are two key technical indicators of the instrument. The transducer is a non-linear capacitive load. The impedance matching can be used to enhance the active power and broaden the working frequency band. This article combines the multi-mode equivalent circuit of the transducer with the impedance matching network. And the circuit grid equation is utilized to obtain the component parameters. Finally, the sound field test is implemented in an anechoic pool, while observing the electrical and acoustic characteristics of the transducer terminal active power, sound field radiation sound pressure, and emission voltage response. The effect of the impedance matching network is evaluated comprehensively. It provides help and guidance for the follow-up ALWD instrument development and experimental testing. Experimental results show that the designed impedance matching network can significantly improve the acoustic radiation performance of the transducer. The frequency bandwidth is expanded by 3. 3 times, the active power is increased by 1. 7 times, the sound pressure is increased by 1. 8 times, and the emission voltage response is increased by 5 dB. The transmit voltage response in the 12~ 16 kHz frequency band is up to 125 dB.
