polyfet rf devices
L8821PR
General Description
Silicon LDMOS transistor designed
specifically for Broadband RF
applications. Suitable for Military
Radios, Cellular Base Staions,
Broadcast FM/AM, MRI, Laser Drivers
and others.
"Polyfet" process features low
feedback and output capacitances,
resulting in high Ft transistors with
high input impedance and high
efficiency.
