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.
