GaAs MES FET
NES1821B-30
30W L-BAND POWER GaAs FET
N-CHANNEL GaAs MES FET
DESCRIPTION
The NES1821B-30 is power GaAs FET which provides
high output power and high gain in the 1.8-2.1 GHz
band.
Internal input matching circuits are designed to
optimize performance. The device has a 0.8
m
m gate
length for increased linear gain. To reduce thermal
resistance, the device uses PHS (Plated Heat Sink)
technology.
The device incorporates WSi (tungsten silicide) gate
