DESCRIPTION
The
LET9130
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 1.0
GHz. The
LET9130
is designed for high gain and
broadband performance operating in common
source mode at 28 V. Its internal matching makes
it ideal for base station applications requiring high
linearity.
