Invited Talk

Increasing the IF bandwidth in heterodyne receivers is one of the main priorities of the ALMA Development Roadmap. One alternative approach to this problem is to increase the number of IF outputs to achieve the same goal of reducing observation time. In this work, we propose the use of a multiband heterodyne receiver architecture in conjunction with digital sideband separation to achieve...
