Millimeter-Wave Transmission-Line Reflectionless Filters
Matthew A. Morgan, Matt Bauwens, Seng Loo +3
We report on the development of transmission-line reflectionless filters operating with passbands at 100 GHz and 230 GHz, and stopband absorption up to 500 GHz, the highest operati…
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…
Reflectionless Filter Topologies Supporting Arbitrary Ladder Prototypes
Matthew A. Morgan, Wavley M. Groves, Tod A. Boyd
Modifications of the authors' previously-published, generalized, lumped-element, reflectionless filter topologies are presented which remove the original constraints on the relativ…
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…
