Description:
The TLTN is a passive RF tri
band coupler designed to
distribute signal within the
master unit when coming
from different bands.
Main operations carried out are:
¾ in downlink it combines a 800MHz to 1000MHz, a 1700MHz to 2000MHz
signal and a 2000MHz to 2200MHz signal into a single RF path
¾ in uplink it filters a composite signal into a 800MHz to 1000MHz, a
1700MHz to 2000MHz signal and a 2000MHz to 2200MHz one.
It is a passive module.

TLTN main applications
Main applications of the TLTN module are:
• Connecting 3 donor sources with different services to one TFLN master
optical TRX in a tri band system, so that:
