Proposed

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

Infrastructure

CDMA2000/W-CDMA Transmitter Applications

Product Description

-A-

Pin 1

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 50Ω operation. Various evaluation board configu-

rations are available to address a broad range of wireless

infrastructure applications:
