Information contained in this document may not be used, applied or reproduced for any purpose unless agreed by Selex ES S.p.A. in writing 57       8.1.5  Switch module – SWITCH The Switch module realizes a "solid state" switch (MOSFET) device for the distribution of the power necessary for the proper working of all the modules of the ECOS-D RBS. 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.

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.
