TMP power supply
Each TMPx-10 power limiter is supplied by the sub-rack back-plane (+12V).
The power consumption of each TMPx-10 is 2W max
TMP insertion loss
TMP insertion loss < 1.7dB.
When designing the system, remember to take into account the insertion loss
of the TMP.
Warnings
The overall input power must not exceed +35dBm.
Inserting or removing TMP modules
• Do not remove or insert any TMP module into TPRN sub-rack before
having switched off main power supply.
• The TMP modules must be handled with care, in order to avoid damage to
electrostatic sensitive devices.
• When installing TMP modules in the sub-rack, take care to alternate active
and passive cards in order to ensure proper heat dissipation.
• In a multi-sub-rack system, remember to assign to each sub-rack a proper
RS485 bus address before installing the modules (please refer to TPRN
section for further details).
TMP installation
The TMP power limiter can be accomodated in any of the 12 slots of a TPRN
active sub-rack.
Note
: In case a new TMP module has to be installed in a still working Master
Unit, switch off the sub-rack before inserting the plug-in TMP module
1. Unpack the kit which include
 1 TMP
 1 RF jumper (SMA-m), 35cm
2. Carefully insert the TMP module in any of the TPRN sub-rack slots and
lock the 4 screws on the front corners.
3. Connect RF cables according to what planned by designer. Use a specific
torque wrench to fix each cable to relevant ports.
4. Switch on the sub-rack. As you switch on the system, carefully refer to
the TFLN Start-up section.
