SAT IF
SAT IF
Launch- and post amplifier for cascading with SMK 99xx F.
SAT IF:
• Aspecialamplifier/filterdesignimprovesthe  
intermodulation properties of the launch amplifiers
considerably
• Thehighselectiveinputfilterguaranteesthat
 interferenceproductsoftheLNBscannotdrivethe
amplifiers into saturation
• Anadditionaloutputfilterensuresthat
intermodulation products and noise effects do not
degrade the terrestrial signal
Terrestrial:
• Forward path:
Terrestrial amplifier with pre emphasis
• Return path:
Selectable: off, passive, active
Gain selectable: 20, 15, 10 or 5 dB
• CATVcompatible
• Pushpulltechnology
• Leveladjusterrange:0...-15dB
