SM724

polyfet rf devices SM724 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.
