DESCRIPTION
The SD57045 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 SD57045 is designed for high gain
and broadband performance operating in
common source mode at 28V. It is ideal for base
stations applications requiring high linearity.
