Description
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.
Each RF Port contains DC blocking Capacitors and a D.C. Bias Network consisting of High Impedance Lines and RF bypass capacitors. This device has 100 um square gold plated bonding pads at all RF and DC ports. RF and DC Ground Backside Gold Plating allows conventional chip bonding techniques using 80Au/20Sn Solder, Indalloy Solder, or Electrically Conductive Silver Epoxy.
