DESCRIPTION
The LET20030C is a common source N-Channel
enhancement-mode lateral Field-Effect RF power
transistor designed for broadband commercial and
industrial applications at frequencies up to 2.0 GHz.
The LET20030C is designed for high gain and
broadband performance operating in common
source mode at 26 V. It is ideal for base station
applications requiring high linearity.
