v04.0120 AMPLIFIERS -LOW NOISE -SMT DUAL OUTPUT LOW NOISE
AMPLIFIER, 0.04 -0.96 GHz
Typical Applications Features The HMC549MS8GE is ideal for: Single-ended or Balanced Output • DTV Receivers High Output IP3: +27 dBm • Multi-Tuner Set Top Boxes Low Noise Figure: 3.5 dB • PVRs & Home Gateways Single Positive Supply: +5V
75 Ohm Input Functional Diagram General Description
The HMC549MS8GE is a GaAs pHEMT MMIC
Low Noise Amplifier that are ideal pre-amplifiers for CATV Set Top Box, Home Gateway, and
Digital Television receiver 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 +5V @
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. Electrical Specifications, 75 Ohm System, TA = +25° C, Vdd = +5V
