RF Power Field Effect Transistors
N--Channel Enhancement--Mode Lateral MOSFETs
Designed for broadband commercial and industrial applications with
frequencies from 470 to 860 MHz. The high gain and broadband performance
of these devices make them ideal for large--signal, common--source amplifier
applications in 50 volt analog or digital television transmitter equipment.
