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.
