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.
