Functional Diagram
General Description
The HMC549MS8G & HMC549MS8GE are GaAs
PHEMT MMIC Low Noise Amplifiers that are ideal
pre-amplifiers for CATV Set Top Box, Home Gateway,
and Digital Television receivers operating between
40 and 960 MHz. This high dynamic range LNA has
been optimized to provide 3.5 dB noise figure and
+27 dBm output IP3 from a single supply of +5.0V @
120 mA. The outputs of this LNA are extremely well
balanced, and can be used to drive a differential input
tuner with very high input IP2 requirements. This dual
purpose LNA can also be used as an active splitter
driving two single-ended input tuners. This LNA is
housed in a RoHS compliant MSOP8G SMT package
with exposed ground paddle.
