RF POWER VDMOS TRANSISTOR
Description
polyfet rf devices
SR401
General Description Silicon VDMOS and LDMOS transistors designed specifically for broadband RF applications.
Suitable for Militry Radios, Cellular and Paging Amplifier Base Stations, Broadcast FM/AM, MRI, Laser Driver and others.
"Polyfet" process features low feedback and output capacitances resulting in high F t transistors with high input impedance and high efficiency.
