SPF5344Z

SPF5344Z 0.8GHz to 4GHz, GaAs pHEMT 2Stage Low Noise MMIC Amplifier SPF5344Z 0.8GHz to 4GHz, GaAs pHEMT 2-STAGE LOW NOISE MMIC AMPLIFIER Product Description The SPF5344Z is a high performance 2-Stage pHEMT MMIC LNA designed for use from 0.8GHz to 4GHz. It offers low noise figure and high linearity in a gain block configuration. Its single-supply operation and integrated matching networks make implementation remarkably simple. The off-chip interstage choke and DC block allow for optimum performance tuning.
