Denis Meledin,Alexey Pavolotsky,Vincent Desmaris,Igor Lapkin,Christophe Risacher,V. Perez,Doug Henke,Olle Nyström,Erik Sundin,Dimitar Milkov Dochev,Miroslav Pantaleev,Mathias Fredrixon,Magnus Strandberg,Boris M. Voronov,Gregory Goltsman,Victor Belitsky +15 more
TL;DR: In this article, the Atacama Pathfinder EXperiment telescope was used for the development, fabrication, and characterization of a balanced waveguide hot electron bolometer (HEB) receiver.
Journal ArticleDOI
Waveguide-to-microstrip transition with integrated bias-T
TL;DR: In this article, a waveguide-to-microstrip transition with an integrated bias-T is presented, which couples the RF field of a full-height waveguide to a microstrip line or directly to an active component.
Journal ArticleDOI
Performance of the First ALMA Band 5 Production Cartridge
Bhushan Billade,Olle Nyström,Denis Meledin,Erik Sundin,Igor Lapkin,Mathias Fredrixon,Vincent Desmaris,Hawal Rashid,Magnus Strandberg,Sven-Erik Ferm,Alexey Pavolotsky,Victor Belitsky +11 more
TL;DR: In this article, the first ALMA Band 5 production cartridge is presented, covering frequencies from 163 to 211 GHz, and the sideband rejection is better than 10 dB over 90% of the observational band.
Journal ArticleDOI
