RF Device Data
Freescale Semiconductor
RF Power Field--Effect Transistor
N--Channel Enhancement--Mode Lateral MOSFET
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 32 volt digital television transmitter equipment.
