Product Description
Features
The SPF5344Z is a high performance 2-Stage pHEMT MMIC LNA designed Low Noise Figure=0.80dB at
2.0GHz
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.
Gain=24.5dB at 2.0GHz
OIP3=39dBm at 2.0GHz
Excellent Return Loss:
