Technical Data
RF Power Field-Effect Transistor
N-Channel Enhancement-Mode Lateral MOSFET
Designed for broadband commercial and industrial applications with frequen-
cies 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 32 volt digital television transmitter equipment.
