The Anatomy of RF Chains: Metrics, Measures, and Operating Efficiency
Leonid Belostotski, Arjuna Madanayake, John Nielsen +6
In 1958, Haus and Adler [1] introduced the concept of noise measure. Noise measure is a single quantitative metric that provides a comprehensive basis for comparing devices (indivi…
Overview of the Canadian Hydrogen Observatory and Radio Transient Detector (CHORD) Project
The CHORD Collaboration, Kevin Bandura, Leonid Belostotski +49
The Canadian Hydrogen Observatory and Radio-transient Detector (CHORD) is a next-generation wideband radio interferometer currently being constructed and commissioned at the Domini…
0.3-to-1.5-GHz LNA with Wideband Noise and Power Matching for Radio Astronomy
Mark Lai, Vincent MacKay, Dallas Wulf +2
This paper presents a low-noise amplifier (LNA) that was developed for a new radio telescope comprised of 512 parabolic dish antennas. The LNA closely interfaces to a custom-made a…
General Framework for Array Noise Analysis and Noise Performance of a Two-Element Interferometer With a Mutual-Coupling Canceler
Leonid Belostotski, Adrian T. Sutinjo, Ravi Subrahmanyan +2
This article investigates the noise performance of a two-element phased array and interferometer containing a recently introduced self-interference canceler, which in the context o…
