SAT IF
SAT IF
For 8 ... 16 SAT IF signals.
The UniSystem multiswitches can be used as stand-alone
devices or can be cascaded with themselves for an easy
extension of the number of subscribers. The UniSystem is
extendable to up to 16 SAT IF levels.
Special features:
• AftertheSATIFsignalhasbeendecoupled
by microstripline directional couplers, it is
amplified for each receiver output, which
produces a tap loss of 3 ... +1 dB
UniSystem - Flexible Multiswitch System 9 in 8
SMS 9989 U, SMS 9987 U
Each receiver output has an
integrated switchable level shifting
(except SMS 9987 U)
9 DC-decoupled terminating resistors
are shipped with the SBK 131309 NF to
terminate the trunk lines.

Possible applications:
1. As a single multiswitch for 8 SAT IF signals
2. In„piggyback“modeinconjunctionwitha
multiswitch relay extensible for 16 SAT IF signals. The
wall mounting frame supplied is designed to support
also the „piggyback“ assembly
3. The master outputs also facilitate cascading, so
that the number of receivers can be increased.
Without amplifying the signal, it is possible
(depending on cable quality and length) to feed up
to 24 receiver
