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 (Gain)
On request, the PABB0001A gain can be change
Note 2 (Load matching)
This amplifier can work without power reduction on a 2:1 VSWR load matching (analog or
digital TV application). In this condition, phase and temperature are irrelevant. Please,
remember that this limit is valid only for digital or analog modulation signals.
Pulsed signal or other kind of modulation can drastically change this limit.
Remember that load mismatch higher than 2:1 can damage the amplifier, a suitable
protection system must be used.
