Dual Band Receiver Design for the Black Hole Explorer (BHEX) Mission
Cheukyu Edward Tong, Keara Carter, Paul Grimes +6
A dual band receiver has been designed for the Black Hole Explorer (BHEX) mission, which is a space Very-Long Baseline Interferometry (VLBI) mission concept, aimed at unveiling the…
Millimeter-Wave Reflectionless Filters Using Advanced Thin-Film Fabrication
Matthew Morgan, Seng Loo, Tod Boyd +1
We report on the development of millimeter-wave, lumped-element reflectionless filters using an advanced thin-film fabrication process. Based on previously demonstrated circuit top…
Reflectionless Filters for Generalized Transmission Functions
Augusto Guilabert, Matthew Morgan, Tod Boyd
Single-ended circuit topologies, and a theorem for the development thereof, are presented with which one may realize constant-resistance (or reflectionless) filters, having ideally…
The Next Generation Very Large Array: A Technical Overview
Robert J. Selina, Eric J. Murphy, Mark McKinnon +14
The next-generation Very Large Array (ngVLA) is an astronomical observatory planned to operate at centimeter wavelengths (25 to 0.26 centimeters, corresponding to a frequency range…
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 Cryogenic SiGe Low Noise Amplifier Optimized for Phased Array Feeds
Wavley M. Groves, Matthew A. Morgan
The growing number of phased array feeds (PAF) being built for radio astronomy demonstrates an increasing need for low noise amplifiers (LNA) that are designed for repeatability, l…
