Product Description
The RF3800 is specifically designed for wireless infrastructure applications at
450MHz and 850MHz. 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 excellent efficiency and thermal stabil-
ity 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
configurations are available to address a broad range of wireless infrastructure
applications.
