The laser control circuit uses advanced circuit design, ensuring reliable and stable operation. Provides excellent AGC characteristics – when the input optical power range is within -7 ~ +2dBm, the RF output level remains unchanged. Optimized circuit design using the SMT production process optimizes the entire signal path, making the optical signal transmission more stable. Professional RF attenuator circuit ensures excellent linear attenuation. GaAs amplifier device provides low distortion and high reliability. Aluminum die casting for efficient cooling and stable performance.
