1 x RF Power Amplifier
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
Active Bias with Adjustable Current
On-Chip Output Power Detector
Is this amplifier lineair?
if so, at what output power is this amplifier still linear.
I want to use this amp for DVB.
