SX501
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"^TM process features
low feedback and output capacitances,
resulting in high F_t transistors with high
input impedance and high efficiency.
