RF Preselector for the Advanced Wideband Digital DAS of VLBI Radio Telescopes

Transactions of IAA RAS, issue 29, 39–42 (2014)

Keywords: preselektor, wideband digital DAS, VLB

Abstract

The research results of the RF preselektor prototype units are presented. It was included in the channel of digital conversion of a wideband digital data acquisition system (DAS). The frequency range is from 100 MHz to 1536 MHz on the -6 dB level. The figure of the amplitude-versus-frequency distortion response is less than 1 dB in this frequency range. The preselektor has an almost lineal phase response in the working frequency band.
