Abstract :
The insertion loss of an experimental high-frequency fiberoptic link is reduced to 7 dB with an 800-MHz (9%) 3-dB bandwidth at 9 GHz by improving the link optical performance and by using reactive passive RF impedance matching. The link signal-to-noise ratio is measured and found to be about 125 dBc/Hz over the 800-MHz bandwidth. This is a significant improvement from the typical X-band RF link insertion loss of 40 dB and could help to open the way to many microwave applications of fiberoptic links in radar and avionics systems
