RF3805
GaAs HBT PRE-DRIVER AMPLIFIER
Typical Applications
• GaAs HBT Pre-Driver for Basestation Amplifiers • Class AB Operation for GSM/EDGE/
• Power Amplifier Stage for Commercial Wireless CDMA2000/W-CDMA Transmitter Applications
Infrastructure
Product Description
The RF3805 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 RF3805 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 50operation. Various evaluation board configu-
rations are available to address a broad range of wireless
infrastructure applications:
• GSM/EDGE1800
• CDMA2000
• W-CDMA
