Abstract

This paper presents an integrated MicroPhotonic beamformer that processes RF-modulated optical signals to adaptively synthesise multiple broadband nulls in smart phased-array antennas. The beamformer is designed to operate at centre frequency of 5.6 GHz with 1 GHz bandwidth. Designs of the different photonic and RF components are presented. Simulation results show that a 4-element MicroPhotonic broadband smart antenna beamformer operating in the 5.1-6.1- GHz range can generate three broadband nulls, with less than 1.121° beam squint.
