Abstract. In this paper we present a new type of cryogenic filter. This filter based on Fabry-Perot interferometer. We use quartz substrate covered by gold grid with low transmission coefficient. Thickness of quartz is 240 um and thickness of gold is 300 nm. The modeling of this filter was done in CST Studio. Filter was tested in room temperature. Backward wave oscillator was used like GHz source and pyroelectric was used like detector. For the cryogenic experiments was used black body (NiCr film on sapphire substrate). Cold-electron bolometer was used for signal detection. This filter can be inserted into cryostat and can be tuned mechanically. Q-factor is 25 and transmission 50% at frequency range from 100 GHz till 500 GHz were observed.

Key words: cryogenic filter, subTHz range, microwave radiation.
