In this paper, an implementation of acoustooptic modulator driven circuit based on FPGA and DDS chip AD9910, with the output signal amplified by a threestage cascaded LT5514, HMC680LP4 and HELA10D power amplifiers, is presented. The performance testing of single frequency output, frequency switching output and frequency sweeping output are carried out. And a 1 572 nm DFB laser diode is used as the source to test the capability of the circuit to drive two different fiber acoustooptic modulators. The experimental results indicate that the output frequency of circuit is tunable from 30 MHz to 300 MHz and the output power is tunable from 20 dBm to 30 dBm. The proposed circuit has great flexibility and can be used to drive different types of acoustooptic modulator.
