The TLCN4 insertion losses vary slightly with the frequency bands, as shown
in table 5.8.
When designing the system, remember to take into account the insertion loss
of the TLCN4.
Warnings
The overall input power must not exceed +24dBm
TLCN4 Installation
Since the TLCN4 module doesn’t require any power supply it can be housed
either in an active or a passive TPRN sub-rack.
1. Unpack the kit which include
 1 TLCN4
 8 RF jumpers (SMA-m), 1 x 18cm, 2 x 23cm, 2 x 28cm, 2 x 33cm,
1 x 36cm
2. Carefully insert the TLCN4 module in any of the TPRN sub-rack slots and
lock the 4 screws on the front corners.
3. Connect RF cables to UL and DL ports, according to what planned by
designer. Use a specific torque wrench to fix each cable to relevant ports.
4. In case some ports remain unused remember to connect them to a 50 Ω
load (not included)
