Design and Development of ALMA Band 4 Cartridge Receiver

摘要

This paper describes the design and development of the ALMA Band 4 cartridge receiver. Band 4 is one of the ten bands that will form the ALMA Front End Receiver. It receives radiation in the 125-163 GHz frequency range in two orthogonal polarizations and down-converts the sideband separated signals to intermediate frequencies between 4 and 8 GHz.
