Hello, I have an amplifier as shown bellow.
my p1dB point is at 30dBm (1 watt)
based n the datasheet What input power it can handle ?
What gain i will get form this input power?
Thanks.

From the data in your picture,the gain of the amplifer is 7-8.5dB,and the output p1dB of amplifier minus the gain of the amplifier is the maximum input power of the amplifier.
 

The input power that the PA can handle is about +23dBm, and the gain at +30dBm output is about 7dB.
Is not mentioned, but I think the small variations of gain, output power and P1dB are vs frequency.
 

To my mind the data sheet is a bit sloppy.
Expect the small signal gain to be anywhere between 6 and 9.5dB over the operating frequency range and temperature.
You should plan for the output at 1db GCP being nearer +28dBm that +30.
Assuming that it will deliver +30dBm, +24dBm or more may be needed to get it.
 

Base on rough calculation:
P1dB output is at +30dBm, the corresponding linear Pin will be +30dBm+1dB - linear Gain (8.5) = +22.5dBm.
