Description
M/A-COM’s SW-419 is a GaAs MMIC SP4T terminated switch in a
low cost SOIC 24-lead wide body surface mount plastic package.
The SW-419 is ideally suited for use where very low power consumption is re q u i red. Typical applications include switch matrices, and filter banks in systems such as: radio and cellular equipment, PCM, GPS, fiber optic modules, and other battery powere d
radio equipment.
The SW-419 is fabricated with a monolithic GaAs MMIC using a
m a t u re 1-micron process. The process features full chip passivation for increased perf o rmance and re l i a b i l i t y .
