More TLCN4 modules can be used in cascade connections.
TLCN4 Insertion Loss
The TLCN4 insertion losses vary slightly depending on the frequency bands, as shown in table
4.8.
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 includes
ÿ 1 TLCN4
ÿ 8 RF jumpers (SMA-m), 1 x 18 cm, 2 x 23 cm, 2 x 28 cm, 2 x 33 cm, 1 x 36 cm
2. Carefully insert the TLCN4 module into any of the TPRN sub-rack slots and tighten the 4
screws on the front corners.
3. Connect RF cables to the UL and DL ports, according to what has been planned by the
designer. Use an appropriate torque wrench to fi x each cable to their relevant ports.
4. In case some ports remain unused, remember to connect them to a 50 Ω load (not
included)
