polyfet rf devices
L8711P
General Description
Silicon VDMOS and LDMOS
transistors designed specifically
for broadband RF applications.
Suitable for Militry Radios,
Cellular and Paging Amplifier Base
Stations, Broadcast FM/AM, MRI,
Laser Driver and others.
TM
"Polyfet" process features
low feedback and output capacitances
resulting in high F _t transistors with high
input impedance and high efficiency.
