LX803

General Description

Silicon VDMOS and LDMOS

transistors designed specifically

for broadband RF applications.

Suitable for Military Radios,

SILICON GATE ENHANCEMENT MODE

RF POWER LDMOS TRANSISTOR

Cellular and Paging Amplifier Base

Stations, Broadcast FM/AM, MRI,

45Watts Single Ended

Package Style LX2

Laser Driver and others.

"Polyfet" process features low

feedback and output capacitances

HIGH EFFICIENCY, LINEAR,

HIGH GAIN, LOW NOISE

resulting in high F transistors with

high input impedance and high

efficiency.
