The 26–36 GHz receiver for a radio astronomy radiometer, to characterize the polarization of the Cosmic Microwave Background, is presented. This receiver is based on very low noise cryogenically cooled amplifiers in the front-end module, while in the back-end module a broadband amplification and direct detection chain is operated at room temperature. Noise temperature of the low-noise amplifier (LNA)...
