DESCRIPTION
The NE72118 is a high performance gallium arsenide metal
semiconductor field effect transistor (MESFET), housed in a
low cost plastic surface mount package (SOT 23 style). This
device's low phase noise and high fT make it an excellent
choice for oscillator applications on a digital LNB (Low Noise
Block).
NEC's stringent quality assurance and test procedures ensure
the highest reliability performance.
