## Four Chanel Distributer of IF Signals for DAS

Transactions of IAA RAS, issue 19, 134–138 (2009)

Keywords: радиоинтерферометрия со сверхдлинными базами, РСДБ-радиотелескоп, система преобразования сигналов, промежуточные частоты, четырехканальный распределитель сигналов, диапазон частот 100-1000 МГц, коммутируемый выход, выходные уровни в пределах 0-18 дБ, сигналы двух поляризаций двух диапазонов длин волн

### Abstract

The results of IF Signals Distributer for DAS working out are represented. The frequency range is 100-1000 MHz. There are four inputs and ten switching outputs in this distributor. The output level is adjusted in 018 dB range. The distortion of amplitude versus frequency response characteristic is less than 1.5 dB in frequency range and less than 0.2 dB in any 32 MHz segment. This fact results from accurate selection of amplifier integrated circuit and from using the special amplitude versus frequency response characteristic correction circuit. Four independent inputs allow to receive simultaneously signals of two polarisations two ranges of wavelengths
