Resumen/Abstract
The radiometers at 30 and 40 GHz for the QUIJOTE radio astronomy experiment are broadband very sensitive receivers to perform scientific sky observations of the Cosmic Microwave Background (CMB). The aim of the QUIJOTE experiment is the measurement of the linear polarization percentage of the received signal. Scientific data will be used for cosmological analysis of the Universe and the indirect detection of gravitational waves. The radiometers are based on cryogenically cooled front-end modules followed by room temperature amplification, correlation and detection modules. Relative bandwidth is around 30%. The radiometers scheme is based on two balanced branches and direct detection.
