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.
