MA4SPS402

MA4SPS402 SurMount™ Series Surface Mount Monolithic PIN Diode Chip Features Surface Mount Diode No Wirebonds Required Rugged Silicon-Glass Construction Silicon Nitride Passivation Polymer Scratch Protection Low Parasitic Capacitance and Inductance High Power Handling (Efficient Heatsinking) Case Style ODS-12531, 2 A B Description M/A-COM’s MA4SPS402 is a silicon-glass PIN diode fabricated with M/A-COM’s patented HMIC™ process. This device features two silicon pedestals embedded in a low loss glass. The diode is formed on the top of one pedestal and connections to the backside of the device are facilitated by making the pedestal side walls conductive. Selective backside metalization is applied producing a surface mount device. The topside is fully encapsulated with silicon nitride and has an additional polymer layer for scratch protection. These protective coatings prevent damage to the junction and the anode air-bridge during handling and assembly. HSP109 C D E D D Applications These devices can be used in series and shunt switches up to 20 GHz where smaller area and profile are required. Low parasitic values of L and C make additional circuit tuning unnecessary. These diodes can also be used for switched pad attenuator circuits. 1. 2. Backside metal: 0.1 micron thk. gold.
