• GaAs HBT Pre-Driver for Basestation Amplifiers • Class AB Operation for GSM/EDGE/CDMA
• Power Amplifier Stage for Commercial Wireless
Infrastructure
Transmitter Applications
Product Description
The RF3802 is specifically designed for wireless infra-
structure applications. Using a highly reliable GaAs HBT
fabrication process, this high-performance dual-stage
amplifier achieves high output power over a broad fre-
quency range. The RF3802 amplifier also provides excel-
lent efficiency and thermal stability through the use of a
thermally-enhanced surface-mount AlN package. Ease of
integration is accomplished through the incorporation of
an optimized evaluation board design provided to achieve
proper 50Ω operation. Various evaluation board bias con-
figurations are available to address a broad range of wire-
less infrastructure applications:
• AMPS/GSM850/EDGE850
• GSM900/EDGE900
• IS-95/CDMA2000/AMPS
