F1005
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 Ft enhance broadband
performance
