local oscillator (LO), plus optimal intermediate frequency (IF) extraction. HEB mixers operating at 4 K are sensitive to bias fluctuations and LO instability, requiring careful system design. This thesis

modelling work, which will allow us to optimize the design of the instruments such as Pollux. We will then measure polarization in prototypes thanks to a test bench built at LIRA. Samples of UV modulators and
