General Description

PATENTED GOLD METALIZED

SILICON GATE ENHANCEMENT MODE

RF POWER VDMOS TRANSISTOR

Silicon VDMOS and LDMOS

transistors designed specifically

for broadband RF applications.

Suitable for Military Radios,

Cellular and Paging Amplifier Base

Stations, Broadcast FM/AM, MRI,

Laser Driver and others.

8Watts Single Ended

Package Style AC

"Polyfet" process features

gold metal for greatly extended

lifetime. Low output capacitance

HIGH EFFICIENCY, LINEAR,

HIGH GAIN, LOW NOISE

and high F enhance broadband

performance
