Product Description
-A-
Pin 1
The RF3805 is specifically designed for wireless infra-
structure applications. Using a highly reliable GaAs HBT
fabrication process, this high-performance dual-stage
amplifier achieves high output power over a broad fre-
quency range. The RF3805 amplifier 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 configu-
rations are available to address a broad range of wireless
infrastructure applications:
