General Description
The HMC549MS8G & HMC549MS8GE are GaAs PHEMT MMIC Low Noise Amplifi ers that are ideal pre-amplifi ers 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 fi gure 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.
