Abstract :
The design parameters, sensitivity analysis and time delay measurements of a photonic true-time delay beamformer for broadband adaptive wireless access networks in the 40 GHz band are presented. The beamforming is achieved by using a multiwavelength laser in combination with a digital delay line based on optical switches and dispersive fibers.
