Product Description

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 50Ω operation. Various evaluation board bias con-

figurations are available to address a broad range of wire-

less infrastructure applications.
