HMC549MS8GE

AMPLIFIERS - LOW NOISE - SMT v04.0120 Typical Applications The HMC549MS8GE is ideal for: DTV Receivers Multi-Tuner Set Top Boxes PVRs & Home Gateways Functional Diagram HMC549MS8GE DUAL OUTPUT LOW NOISE AMPLIFIER, 0.04 - 0.96 GHz Features Single-ended or Balanced Output High Output IP3: +27 dBm Low Noise Figure: 3.5 dB Single Positive Supply: +5V 75 Ohm Input 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.
