Broadband Continuously Tuneable Delay Microwave Photonic Beamformer for Phased Array Antennas

In this paper a microwave photonic broadband true time delay (TTD) continuously tuneable beamformer module for phased array antenna applications is presented. This microwave photonics beamformer is based on the hybrid integration of Indium Phosphide and Silicon Nitride chips. This paper features results from the latest transmit microwave photonic beamformer based on a completely integrated photonic assembly interface.
