Data on Frequency Research Discussed by Researchers at National Research Council [Performance of the Production Band 3 receivers (84-116 GHz) for the Atacama Large Millimeter Array (ALMA)]

By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Frequency Research. According to news reporting out of Victoria, Canada, by NewsRx editors, research stated, "This paper presents the performance of production Band 3 receivers (84-116 GHz) for the Atacama Large Millimeter Array (ALMA) that operate in Chile at 5000 m altitude. The fabrication, and testing of a total of 73 receivers necessitated stringent quality control during assembly and custom designed automated test set for accurate and reproducible measurement results."

Our news journalists obtained a quote from the research from National Research Council, "Interfaces to the ALMA receiver system are described in details. The average single side band noise temperature of band 3 production receivers is 33.2 K, with a minimum of 24.4 K and a maximum of 45.5 K. As for image rejection, the average is 18 dB, with a minimum at 12 dB and a maximum of 21 dB. Other performances with test methodology are described such as gain variation within the IF band, the gain and phase stability, gain compression, and beam patterns."

According to the news editors, the research concluded: "This paper also describes the interfaces to the ALMA front end system, the testing methodology used, and the test results."
