Abstract

This paper describes the design of a variable S-band delay line based on fiber-optic technology. A combination of a switched-RF configuration and switched-fiber configuration has resulted in improved performance with reduced costs compared to previously reported delay line systems. The reported delay line provides variable delays programmable from 0 nsecs to 9.55 /spl mu/secs in 50 nsec increments and may be switched as quickly as 600 nsecs. The delay line achieved a worst case output noise floor <-55 dBm/MHz, an output SNR>60 dB/MHz with the input signal at the 1 dB compression level of 6.6 dBm, a gain linearity

可变s波段光纤延迟线的设计

本文介绍了一种基于光纤技术的可变s波段延迟线的设计。与先前报道的延迟线系统相比，交换射频配置和交换光纤配置的组合提高了性能，降低了成本。报告的延迟线提供可变延迟，可在50 nsec增量中从0 nsec到9.55 /spl mu/sec进行编程，并且可以快速切换到600 nsec。在最坏情况下，延迟线的输出本底噪声为60 dB/MHz，输入信号的1db压缩电平为6.6 dBm，增益线性度
