The MA4CG6774 is a 77 GHz SP3T Switch made from Gallium Arsenide PIN Diodes, and semi-insulating GaAs Substrate designed for Automotive Applications. These diodes are fabricated on OMCVD epitaxial wafers using a process designed for repeatable electrical characteristics and extremely low parasitics. These Diodes are fully passivated with Silicon Nitride and have an additional layer of Polymide for scratch protection. This protective coating prevents damage to the junction during automated or manual handling. These devices are suitable for pick and place insertion.
