SILICON GATE ENHANCEMENT MODE
transistors designed specifically
for broadband RF applications.
Suitable for Military Radios,
Stations, Broadcast FM/AM, MRI,
Laser Driver and others.
"Polyfet" process features
gold metal for greatly extended
lifetime. Low output capacitance
and high F enhance broadband
