HMC549MS8G / 549MS8GE v02.0310 AMPLIFIERS - LOW NOISE - SMT 7 DUAL OUTPUT LOW NOISE AMPLIFIER, 0.04 - 0.96 GHz Typical Applications Features The HMC549MS8G(E) 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 HMC549MS8G(E) 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.
