Application Note
Read carefully the following information, before design the system integration of this
amplifier. Please remember that Italmec engineers are available to help customers in any
design activity.
Note 1 (Thermal exchanger requirements)
Max operating temperature is measured very closed to the device flange and is referred to
the nominal operative condition. In case of different working conditions, this limit can be
different. Please contact our technical department for further information.
Note 2 (Load matching)
This amplifier can work without power reduction on a 2:1 VSWR load matching. In this
condition phase and temperature are irrelevant. Please, remember that this limit is valid only
for digital and analog signals. Other kind of modulation can drastically change this limit.
Note 3 (Protections)
In order to take the amplifier safe in any working conditions, please add these protections in
the final equipment.
a) Overdrive protection
If the input power of pallet exceed 2dB over the nominal, the device can be damaged, please
use an appropriate fast protection to reduce or switch off the input signal.
b) Reflected power protection (note 2),
A suitable protection system should switch off (or reduce) the input power in case of
excessive reflected power.
c) Thermal protection
Switch off supply voltage if device flange temperature exceeds 85C° when amplifier works at
full power.
