Performance of a highly sensitive, 19-element, dual-polarization, cryogenic L-band Phased Array Feed on the Green Bank Telescope
D. Anish Roshi, W. Shillue, B. Simon +26
A new 1.4 GHz 19-element, dual-polarization, cryogenic phased array feed (PAF) radio astronomy receiver has been developed for the Robert C. Byrd Green Bank Telescope (GBT) as part…
A Highly-Sensitive Cryogenic Phased Array Feed for the Green Bank Telescope
D. Anish Roshi, W. Shillue, J. R. Fisher +15
In this paper, we describe the development of a new L-band (1.4 GHz) Cryogenic Phased Array Feed (PAF) system, referred to as the GBT2 array. Results from initial measurements made…
Custom Chipset and Compact Module Design for a 75-110 GHz Laboratory Signal Source
Matthew A. Morgan, Tod A. Boyd, Jason J. Castro
We report on the development and characterization of a compact, full-waveguide bandwidth (WR-10) signal source for general-purpose testing of mm-wave components. The MMIC-based mul…
Unformatted Digital Fiber-Optic Data Transmission for Radio Astronomy Front-Ends
Matthew A. Morgan, J. Richard Fisher, Jason J. Castro
We report on the development of a prototype integrated receiver front-end that combines all conversions from RF to baseband, from analog to digital, and from copper to fiber into o…
