7.1.3 SWITCH module
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 12 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 12 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%).

7.1.7 Power Amplifier module - PA
The “Power Amplifier” (PA) module is a wide band RF amplifier in VHF (136 - 170 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.
SELEX Communications

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.
