Abstract

The combination of the traveling wave OMT device and the ultra-low-noise MMIC amplifiers has allowed us to develop a broadband 6-8 GHz receiver with a noise temperature of around 10 K. The combination of receiver noise and the additional noise contributions by the telescope optics gives an overall receiver temperature of around 28 K and 34 K in the two polarizations. The large collecting area of the telescope gives rise to a system equivalent flux density of around 4.5 Jy at 7 GHz
