In particular its primary task is to distribute the 13,2 Vdc nominal voltage (Master voltage) and 7 Vdc nominal voltage (Slave voltage). The 7 Vdc Slave voltage is used by all the other modules to power their logic. It is generated by the switch module for direct conversion from the 13,2 Vdc Master voltage. The switch module provides: • ON / OFF of all the modules on the same RBS • Protection against Extra Current (short circuit or overload > 22 A ± 5%) • Protection against Extra voltage (maximum input voltage equal to 30 Vdc ± 5%) • Protection against voltages outside the guaranteed operating range [10.8 ÷ 15.6 Vdc]. • Protection against reverse polarity input voltage. • Protection against over temperature inside the module itself (≥ 100 ° C ± 1%). The front panel is provided with bi-color leds to help in troubleshooting the system.

SELEX Communications Information contained in this document may not be used, applied or reproduced for any purpose unless agreed by SELEX Communications S.p.A. in writing 55 July 2010 8.1.6 Power Amplifier module - PA The “Power Amplifier” (PA) module is a wide band RF amplifier in UHF (450 - 526 MHz). Their time of TX ramp up/down is less than 1200 µsec. This makes the module compatible with the stringent demands of digital transmission. Thanks to a microprocessor mounted on board, the module is able to implement the PUFF technology (Powerful Universal Forming Function) for the shaping of transient power in order to obtain compliance with the rapid transient rules of ACP (Adjacent Channel Power). The microprocessor also manages completely the operation of the module: this would remove any calibration procedures. All configuration changes are performed via software. Other main functionalities are: • continuous transmitter’s operations (100% duty cycle). • Output power selectable between two values (Phi and Plo), each of which can be SW set to a nominal value between 10 and 110 Watts. • final stage protected against excessive mismatching output power. In the case that VSWR remains above a set threshold (eg ReturnLoss = 5dB) for more than a fixed time, the module is able to send an alert and the output power will not exceed a safety value (eg ≤ 10watt). • temperature threshold alarm: if the temperature remains above a set value for more than a fixed time, the module is able to send an alert and will ensure that the RF output power will not exceed a predetermined safe value. The front panel is provided with bi-color leds to help in troubleshooting the system. The table below describes the meaning of the leds: LED Color Label Description 1 Green PWR High High Power level selected and correctly On Air Red PWR fail Emitted power less than a FW configured threshold (3 dB typical) 2 Green PWR low Low Power level selected and correctly On Air Red VSWR On Air and VSWR level is greater than FW configured threshold 3 Green Control bus busy Activity on the control bus
