The installation of CSIRO-designed monolithic microwave integrated circuit (MMIC) amplifiers in the Australia Telescope Compact Array (ATCA), to observe radio signals at wavelength down to 3mm, represented a world first for a radio telescope array. The image above shows a 85 - 115 GHz MMIC low-noise amplifier mounted in a cryogenically coolable package with waveguide input and output connections. [Source: CSIRO]
