Upgrade of EMIR's Band 3 and Band 4 Mixers

Authors:
D. Maier, J. Reverdy, D. Billon-Pierron, and A. Barbier
Abstract:
The Eight MIxer Receiver (EMIR) is a multi-band millimeter wave receiver installed since 2009 at the 30m telescope of the Institut de RadioAstronomie Millimétrique (IRAM) at Pico Veleta in Spain. In autumn 2011, Band 3 and Band 4 will be equipped with state-of-the-art sideband-separating mixers with 8 GHz IF bandwidth. For Band 3 a sideband-separating mixer has been developed within the European project AMSTAR+ in order to replace the currently employed single-sideband mixer. The new mixer has a twice as large IF bandwidth than the current one thus doubling the continuum sensitivity of the receiver. The mixer currently installed in Band 4 will simply be upgraded to 8 GHz IF bandwidth by changing its IF components.
