DANIELS ELECTRONICS SUCCESSFULLY COMPLETES $1.3 MILLION CONTRACT TO ASSEMBLE AND TEST RADIO TELESCOPE RECEIVERS
Victoria, B.C. Canada – March 16th, 2012 - Daniels Electronics Ltd., an international leader in the design, manufacture and service of specialized radio communications systems today announced it has successfully completed a $1.3 Million contract with the Canadian government for the assembly and test of radio receivers used in the National Research Council of Canada (NRC) development of 84-116 GHz heterodyne receivers for the international Atacama Large Millimeter array (ALMA) telescopes awarded back in late 2008.
ALMA is located at 5000m elevation in the Chajnantor Plain of northern Chile. The resolution and sensitivity of the array will constitute a great leap forward compared to existing facilities, making it the world’s pre-eminent radio astronomy facility of the next decades. NRC’s contribution to the project is 73 extremely sensitive 84-116 GHz receivers. The nucleus of the receiver is a superconductor-insulator-superconductor (SIS) tunnel mixer which down converts the RF signal collected by the radio telescope to an intermediate frequency (IF) signal centered at 6 GHz with a bandwidth of 4 GHz. A cryogenic high electron mobility transistor (HEMT) amplifier is used to amplify the IF signal by more than 30 dB before it is delivered to the ALMA Back-End System. The SIS detector and the HEMT IF amplifier must operate at a cryogenic temperature of 4 Kelvin. NRC has developed a cryogenic 4-8 GHz HEMT amplifier for this application.
"Daniels has been very pleased to be a part of this prestigious project and to contribute our expertise in precision assembly and testing of radio electronics for the National Research Council of Canada," says Robert Small, President and Chief Operating Officer with Daniels Electronics. "The ability of a local Victoria company to compete, win and deliver ahead of schedule such advanced technology shows the depth of the high tech industry in Victoria and the level of expertise companies such as Daniels Electronics bring in support of our government's leading edge scientific developments."
