At present, the mature laser driver chips are all digital driver chops for digital optical output, which cannot meet the driving requirements of broadband analog laser in satellite communication, radar, and other fields. In this paper, the butterfly packaging distributed feedback laser module is used. Through the improvement of automatic power control(APC) circuit, automatic temperature control(ATC) circuit and working parameter detection circuit, a drive circuit suitable for analog laser is designed. The average amplitude response gain of the drive circuit is 2 dB, the roughness is 0.6 dB, and the maximum input voltage standing wave ratio and output input voltage standing wave ratio are 1.37 and 1.3 respectively.
