Tri-band receivers for the INAF radio telescopes: from procurement to acceptance tests

Tri-band receivers for the INAF radio telescopes: from procurement to acceptance tests

In less than 30 months, three different tri-band receivers have been developed for the three Italian radio telescopes. The receivers allow simultaneous observation of three different frequency bands: 18-26 GHz, 34-50 GHz and 80-116 GHz. Each receiver delivers at its output ports a total of 112 GHz b...

Description
Summary:In less than 30 months, three different tri-band receivers have been developed for the three Italian radio telescopes. The receivers allow simultaneous observation of three different frequency bands: 18-26 GHz, 34-50 GHz and 80-116 GHz. Each receiver delivers at its output ports a total of 112 GHz bandwidth in two polarizations. The receivers have been designed, fabricated and tested in KASI laboratories and will be mounted in the secondary foci of the INAF radio telescopes as soon as several upgrades to the infrastructures are completed.
