Product Description
The RF3827 is a general purpose, low-cost, high-linearity RF amplifier IC.
The device is manufactured on a Gallium Arsenide process and is featured
in a 3mmx3mm, 16-pin, QFN package. It has been designed for use as an
easily cascadable 75Ω gain block with a noise figure of less than 2dB.
Gain flatness better than 0.5dB from 5MHz to 1000MHz, and high linear-
ity make this part ideal for cable TV applications. Other applications
include IF and RF amplification in wireless voice and data communication
products operating in frequency bands up to 1000MHz. The device is self-
contained with 75Ω input and output impedances providing less than 2:1
VSWR matching. For higher input and output return losses, see the evalu-
ation schematic.
