TL;DR: In this paper, the APEX facility instrument was installed on the telescope at the site of Lliano Chajnantor in northern Chile and the main objective of the paper is to introduce the new instrument to the radio astronomical community.
Journal ArticleDOI
Wideband and High-Gain Corporate-Fed Gap Waveguide Slot Array Antenna With ETSI Class II Radiation Pattern in $V$ -Band
TL;DR: In this article, a multilayer corporate-fed slot array antenna with wide impedance bandwidth and high efficiency was proposed, which consists of three unconnected metal layers based on the recently introduced gap waveguide technology.
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
A 0.8 mm heterodyne facility receiver for the APEX telescope
Christophe Risacher,Christophe Risacher,Vessen Vassilev,Raquel Monje,Igor Lapkin,Victor Belitsky,Alexey Pavolotsky,Miroslav Pantaleev,Per Bergman,Per Bergman,Sven-Erik Ferm,Erik Sundin,Mattias Svensson,Mathias Fredrixon,Denis Meledin,Lars-Göran Gunnarsson,Magne Hagström,L.-Å. Johansson,Michael Olberg,Roy Booth,Hans Olofsson,L.-Å. Nyman +21 more
TL;DR: In this article, the first facility receiver for the band 0.79-1.07 mm (279-381 GHz) was installed together with backends providing down to 60 kHz spectral resolution.
Journal ArticleDOI
Compact Integrated Full-Duplex Gap Waveguide-Based Radio Front End For Multi-Gbit/s Point-to-Point Backhaul Links at E-Band
