4.6. RF Dual Band Coupler TLDN
Description:
The TLDN is a passive RF dual band coupler
designed to distribute signals within the
master unit when coming from different
bands.
Main operations carried out are:
ÿ
in downlink, it combines a low band RF
signal (800MHz to 1000MHz) and a high
band RF signal (1700MHz to 2200MHz)
into a common RF path
ÿ
in uplink, it fi lters the composite signal
into a low-band (800MHz to 1000MHz)
and a high-band (1700MHz to 2200MHz)
It is a passive module.
RF Ports
• 1 UL common RF input port (“C”) for the
combined UL signal
• 1 UL high-band RF output port
• 1 UL low-band RF output port
• 1 DL common RF output port (“C”) for
the combined DL signal
• 1 DL high-band RF input port
• 1 DL low-band RF input port
TLDN Main Applications
Main applications of the TLDN module are:
• Connecting 2 donor sources with different services to one TFLN master optical TRX in a
dual band system, so that:
ÿ
the TLDN combines the DL inputs coming from the 2 different donor sources
