HMC549MS8G / 549MS8GE
General Description
Features
Functional Diagram
The HMC549MS8G(E) is a GaAs PHEMT MMIC
Low Noise Ampli er that are ideal pre-ampli -
ers 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 gure 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.
Single-ended or Balanced Output
High Output IP3: +27 dBm
Low Noise Figure: 3.5 dB
Single Positive Supply: +5V
75 Ohm Input
Electrical Speci cations, 75 Ohm System, TA = +25° C, Vdd = +5V

The circuit board used in the application should use
RF circuit design techniques. Signal lines should
have 75 Ohm impedance while the package ground
leads and exposed paddle should be connected
directly to the ground plane similar to that shown.
A sufficient number of via holes should be used to
connect the top and bottom ground planes. The
evaluation circuit board shown is available from
Hittite upon request.
