GaAs HBT PRE-DRIVER AMPLIFIER
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
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 incorporation of an optimized evaluation board design provided to achieve proper 50 Ω operation. Various evaluation board configurations are available to address a broad range of wireless infrastructure applications: GSM/EDGE1800 CDMA2000 W-CDMA Optimum Technology Matching® Applied
