The RF3809 is a GaAs pre-driver power amplifier, specifi-
cally designed for wireless infrastructure applications.
Using a highly reliable GaAs HBT fabrication process,
0.196
this high-performance single-stage amplifier achieves
0.189
high output power over a broad frequency range. The
RF3809 also provides excellent efficiency and thermal
stability through the use of a thermally-enhanced surface-
mount plastic-slug package. Ease of integration is accom-
plished through the incorporation of an optimized evalua-
tion board design provided to achieve proper 50Ω
operation. Various evaluation boards are available to
address a broad range of wireless infrastructure applica-
tions: NMT 450MHz; GSM850MHz; GSM900MHz;
DCS1800MHz; PCS1900MHz; and, UMTS2200MHz.
