Core ICs and Semiconductors
Rio Systems offers a wide range of solutions for phased arrays, spanning core IC solutions across multiple frequency bands , modeling, calibration, and automation, engineered to meet stringent side-lobe and gain requirements, support simultaneous multi-user operation, enable high antenna gain, and mitigate interference.
A complete set of tools and user customization options are provided, enabling customers to calibrate the system under real-world conditions to achieve the lowest phase and amplitude errors, achieve phase and amplitude matching between channels, and ultimately reduce the uncertainty between estimated and measured antenna beam patterns.
Understanding beamforming impairments in real-world phased-array implementations is essential for achieving the expected performance of an AESA-based system. This white paper is provided to help customers recognize and address the practical challenges that arise during system integration and deployment.
