Abstract
This paper describes the design of the Band 9 receiver cartridges for the
Atacama Large Millimeter Array (ALMA). These are field-replaceable heterodyne
front-ends offering high sensitivities, 602-720 GHz frequency coverage, 4-12
GHz IF bandwidths, and high quasioptical efficiencies. Because the project
will ultimately require 64 cartridges to fully populate the ALMA array, two
key aspects of the design of the Band 9 cartridge have been to take advantage
of commercial manufacturing capabilities and to simplify the assembly of the
cartridge. Preliminary test results of the first (prototype) cartridge are
also presented.
