Abstract
PURPOSE:To make the lowering in cost of the device and to make the device small in size, by applying the base band to a filter device from a reception amplifier having the distributing function of an ultragroup converter and applying this output to a transmission amplifier having the coupling function for the ultragroup converter. CONSTITUTION:The base band from a station A is applied to an ultragroup converter 2 and transmitted to a terminal 2-21 by a reception amplifier 2-3 having the function of distribution via a variable attenuator 2-2. The base band at the terminal 2-21 is applied to a filter 4-2 via a terminal 4-1 of a filter 4. The pass band is determined for the filter 4-2 with line constitution. The ultragroup selected at the filter 4-2 is applied to a transmission amplifier 3-14 having the coupling function via a terminal 3-22 of an ultragroup converter 3 from a terminal 4-3 and transmitted to a station C via a variable attenuator 3-15 from a terminal 3-16.
