RF3802
GaAs HBT PRE-DRIVER AMPLIFIER
The RF3802 is specifically designed for wireless infrastructure applications. Using
a highly reliable GaAs HBT fabrication process, this high-performance dual-stage
amplifier achieves high output power over a broad frequency range. The RF3802
amplifier also provides excellent efficiency and thermal stability through the use of
a thermally-enhanced surface-mount AlN package. Ease of integration is accom-
plished through the incorporation of an optimized evaluation board design provided
to achieve proper 50
Ω operation. Various evaluation board configurations are avail-
able to address a broad range of wireless infrastructure applications:
• AMPS/GSM850/EDGE850
• GSM900/EDGE900
• IS-95/CDMA2000/AMPS
