摘　　要：基于光纤的大带宽、低损耗、抗电磁干扰等优点,将低功率微波信号的接收在光域完成,在保证极低引入噪声、有效抑制镜像信号、简化系统复杂性的同时兼具抗电磁干扰性,实现了集放大、滤波与下变频功能的一体化接收。Based on the advantages of large bandwidth, low loss and anti electromagnetic interference of optical fiber,the reception of low-power microwave signals is completed in the optical domain, while ensuring extremely low introduced noise, effectively suppressing image signal and simplifying system complexity, it also has anti electromagnetic interference, it realizes the integrated reception of amplification, filtering and down conversion.

关 键 词：电磁干扰 噪声 下变频
