SAT IF
SAT IF
Power Launch Amplifier for cascading with SMK 17xx9 F (A)
SAT IF:
• Synchronousleveladjusterforeach
SAT IF system
• Aspecialamplifier/filterdesignimprovesthe
intermodulation properties of the launch amplifier
considerably
• Thehighselectiveinputfilterguaranteesthat
interferenceproductsoftheLNBscannotdrive
the amplifiers into saturation
• Anadditionaloutputfilterensuresthatintermodulation
products and noise effects do not degrade the
terrestrial signal
Terrestrial:
• Theterrestrialinputispassiveandreturnpath
compatible with the possibility of a 18 V (250 mA) remote
current in both directions for an amplifier.
Miscellaneous:
• Selectivestandbyfunction:
If all subscribers only watch TV programms of SAT system
A,onlytheappropriateLNBissuppliedwithpower.The
internallogicturnsoffthepowersupplyofallotherLNBsas
well as that of the integrated amplifiers.
This process results in significant energy savings!
