Description
The SD57120 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 SD57120 is designed for high gain
and broadband performance operating in
common source mode at 28V. Its internal
matching makes it ideal for base station
applications requiring high linearity.
