SAT IF
SAT IF
Power Launch Amplifier for cascading with SMK 13xx3 F(A).
SAT IF:
• Thepowerlaunchamplifierfeatures12SATIFtrunkline 
inputs and outputs in total for reception and distribution
of 4 SAT IF signals of each SAT system A, B and C
• ToensurelogicalallocationoftheIFsignalsaccording 
to the DiSEqC circuit criteria, the IF signals must be
connected to the power launch amplifier according to
the marking on the unit
• AllIFamplifiersfeatureanintegrated6dBslope.
Each SAT system features a synchronous level controller.
 Thusanadjustmentofdifferentsignalsupto10dBis 
possible.
Terrestrial:
• Theterrestrialinputisreturnpath
compatible. Supply voltage selectable in both
directions: 0 V / 18 V (500 mA)
Miscellaneous:
