Product Description
The RFPA3800 is a single-stage GaAs HBT power amplifier specifically designed for
high power, high efficiency applications. It is also well-suited for Wireless Infrastruc-
ture linear power amplifier applications. The RFPA3800 can be optimized for linear
or saturated operation by varying the quiescent bias point and load line. It also
offers low noise figure making it an excellent solution for 2nd and 3rd stage LNAs.
The RFPA3800 exhibits excellent thermal performance through the use of a ther-
mally-enhanced plastic surface-mount slug package.
