AMPLIFIERS
Multi-Amplifi er
At huge SAT IF distribution systems it may be necessary to use multi-amplifi er
components for tapped signals in order to level the SAT IF signals. There are
models with 5 and 9 inputs and outputs with a gain of 20 dB. Every input
(TERR + SAT) is equipped with an attenuation controller by 15 dB. They are
fed by the power supply units of the SAT IF system (e.g. via the power supply
unit of the multiswitch). The power supply unit SDP 152 (15 V/2 A) is optio-
nally available if it is necessary!
