Here is the data sheet (click on PROCEED):

The output power is probably about 0.5 .. 1 Watt if you prefer to be in the linear range.

PA Device is discontinued, but P1dB is listed as 35dBm by Qorvo which seems quite good.
Although this performance probably will be less on cheap FR4 PCB.P1dB=35dBm at 6V
Three Stages of Gain: 37dB
802.11g 54Mb/s Class AB Performance
POUT=27dBm at 2.5%EVM, VCC
6V, 878mA
Active Bias with Adjustable Current

Is this amplifier lineair?
if so, at what output power is this amplifier still linear.
I want to use this amp for DVB.

Hallo,
is there anyone who measured an amplifier with the SZM2166? The gain is lower than expected. The datasheet shows three stages compared to the SZA244.
I would like to see some S21-Measurement and if possible an intermodulation spectrum.
Thanks
