Description
The SD56120 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 SD56120 is designed for high gain
and broadband performance operating in
common source mode at 28 V. It is ideal for
broadcast applications from 470 to 860 MHz
requiring high linearity.
