An Output Signal Stability Analysis of the Radio Telescope Wideband Receiving System Prototype

Transactions of IAA RAS, issue 44, 18–25 (2018)

Keywords: wideband receiver, superheterodyne receiver, Allan Variance, gain stability, phase stability, fluctuation.

Abstract

The measurement technique and results of the gain amplitude and phase stability measurements of the wideband receiving system prototype for the RT-13 radio telescope are presented in this paper. The main sources of fluctuations and their types are identified on different time scales using the Allan Variance. The fluctuation impact on the overall receiver stability is determined at some stages. Gain fluctuations of cryogenic amplifiers and the influence of transistor parameters on its fluctuations are investigated.
