GaAs HBT PRE-DRIVER AMPLIFIER
• Pre-Driver for 450MHz Basestation Amplifiers
• PA Stage for Commercial Wireless Infrastructure
• Class AB Operation for Cellular Radio and
Wireless Local Loop
The RF3800 is specifically designed for wireless infra-
structure applications in 450MHz. Using a highly reliable
GaAs HBT fabrication process, this high-performance
single-stage amplifier achieves high output power over a
broad frequency range. The RF3800 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 50
Ω operation. Various evaluation board bias con-
figurations are available to address a broad range of wire-
less infrastructure applications.
• 6W Output Power
• High Linearity
• 45% Power-Added Efficiency
• Thermally-Enhanced Packaging
• Broadband Platform Design Approach
