Abstract :
Receivers for the Atacama Large Millimeter/submillimeter Array are designed to include 10 frequency bands, and results are presented here for the Band 3 (84-116 GHz) and Band 6 (211-275 GHz) cryogenically cooled dual-polarization, signal-sideband receivers. A total of 73 such receivers were constructed for each band.
