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.

"Polyfet"

process features

low feedback and output capacitances,

resulting in high F transistors with high

input impedance and high efficiency.
