TLCN2
More TLCN2 modules can be used in cascade connections.
TLCN2 Insertion Loss
The TLCN2 insertion loss varies slightly depending on the frequency bands, as shown in table
4.7.
When designing the system, remember to take into account the insertion loss of the TLCN2, if
700-1400MHz 1400-2200MHz 2200-2500MHz
TLCN2 insertion loss 3.7 ± 0.4dB 4.1 ± 0.5dB 4.6 ± 0.4dB
present.
Warnings
The overall input power must not 24dBm.
TLCN2 Installation
Since the TLCN2 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 TLCN2
ÿ 4 RF jumpers (SMA-m), 2 x 25 cm, 2 x 35 cm
2. Carefully insert the TLCN2 module into any of the TPRN sub-rack slots and lock 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 its relevant ports.
4. In case some ports remain unused, remember to connect them to a 50 Ω load (not
included)
