Typical Applications
• GaAs HBT Pre-Driver for Basestation Amplifiers
• Power Amplifier Stage for Commercial Wireless
Infrastructure
Product Description
The RF3805 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 RF3805 amplifier also provides excellent efficiency and thermal stability through the use of a
thermally-enhanced surface-mount AlN package. Ease of
integration is accomplished through the incor poration of
an optimized evaluation board design provided to ach ieve
proper 50 Ω operation. Various evaluation board configurations are available to address a broad range of wireless
infrastructure applications:
• GSM/EDGE1800
•CDMA2000
•W-CDMA
