In this paper we will describe the characterisation of a rf ampliﬁcation chain based on a travelling wave parametric ampliﬁer (TWPA). The detection chain is meant to be used for dark matter axion searches and thus it is mounted coupled to a high Q microwave resonant cavity. A system noise temperature T sys = (3 . 3 ± 0 . 1) K has been measured at a frequency of 10.77 GHz, using a novel scheme allowing measurement of T sys exactly at the cavity output port.
