polyfet rf devices
P123
General Description
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" ^TMprocess features
gold metal for greatly extended
lifetime. Low output capacitance
and high F_t enhance broadband
performance
