ALMA Band 2 Cold Cartridge Assembly Design
Paper in proceeding, 2022
As part of the ALMA development, we present the
design of the ALMA Band 2 Cold Cartridge Assembly (CCA). The
Band 2 is the last band that completes the suit of the 10 receiver
channels of ALMA. The originally planned ALMA Band 2
receiver cartridge should cover the RF band of 67 - -90 GHz. The
recent progress in technology, optics, OMT design and mm-wave
amplifiers, however allowed to implement receiver that has an
extended RF band up to 116 GHz. Furthermore, the Band 2
receiver pursues 2SB layout and provides 4-18 GHz IF band for
two sidebands in a dual-polarization configuration. Here, we
describe the design of the Band 2 CCA that includes optics,
amplifier assembly, internal RF transport, mechanics and
cryogenics. The downconverter part and performances are
described elsewhere.
