The TDU901 Touch-Screen is existing in two variants. The Var. 02 is the standard con-
figuration with mechanical holder and coated front plate. The Var. 03 is extended with a
front LOCAL LAN connection for more convenient LAN cabling (local operation with
Laptop).
If the USB Display Var. 03 is ordered together with a 2HU TLx9 Backup TX System it is
mandatory to order also the option LOCAL LAN2 for the system control device, other-
wise the local LAN control at the front is not possible.
3.1.4.15 Power Amplifier Module
The amplifier-pallet operates from 470 MHz to 790 MHz. The whole amplifier stage is
designed as a fixed gain amplifier without any compensation of gain and temperature
and frequency response. There is no internal power or gain control. The entire FPGA-
based power control is done on the Exciter / GapFiller board by a variable gain ampli-
fier (VGA) and a voltage variable attenuator (VVA). The detection of the output power
is done on the TLx9 PA module.
Fitting variants:
●
PA Pallet and 200 W heat sink and 2 fans
●
PA Pallet and 100 W heat sink and 1 fan
●
PA Pallet and 50 W heat sink and 1 fan
