Delaware Patent of the Month – October 2023
Phase Sensitive Innovations Inc (PSI) have built a reputation based on their specialty photonic technology which enable phased array antenna systems to physically image the radiofrequency (RF) environment. Being at the forefront of their industry, the company continually strives to innovate new solutions and maintain their edge.
Recently, conformal, low profile, and wideband phased antenna arrays have been garnering more attention. These technologies operate over several octaves of frequencies and support various applications including both radar and communications. PSI has identified this growing area of interest and designed a modular antenna system that operates over ultra-wide frequency bands.
The design is a swappable modular-based RF frontend which can be reconfigured as needed to be either a transmitting or receiving phased array system. The frontend then works with the unique spatial and spectral optical processing of complex RF signals over ultra-wide frequency bands.
The optical processor’s multiple electro-optical modulators work in harmony to generate combined modulated light beam pairs, each meticulously controlled in both phase and amplitude. This level of precision is a game-changer for RF transmission.
What truly sets this modular RF transmitter apart is its adaptability. Designed with modularity as a guiding principle, it allows for easy configuration for various applications. The optical processing engine can be directly connected to a variety of RF antenna array modules through RF connectors. This means you can customize your transmitter to suit specific needs without the need for major overhauls.
PSI has seamlessly integrated an RF amplifier module which collaborates effortlessly with the optical processing engine, amplifying the RF signals generated by photodiodes. Not only does this boost the signal, but it also ensures efficient transmission to the RF antenna array module. A series of antenna elements work hand in hand with the photodiodes to receive RF signals. These elements are directly connected to their corresponding photodiodes, creating a streamlined signal path. As with the other components, this module can be detached and replaced with ease, providing an unprecedented level of adaptability.
