Description
The MA4E2544L-1282 Series SurMountTM Low Barrier, Silicon Schottky Cross-Over Quad Diodes are fabricated with the patented Heterolithic Microwave Integrated Circuit (HMIC) process. HMIC circuits consist of Silicon pedestals which form diodes or via conductors embedded in a glass dielectric, which acts as the low dispersion, low loss, microstrip transmission medium. The combination of silicon and glass allows HMIC devices to have excellent loss and power dissipation characteristics in a low profile, reliable device.

Features
■ Extremely Low Parasitic Capitance and Inductance
■ Surface Mountable in Microwave Circuits, No Wirebonds Required
■ Rugged HMIC Construction with Polyimide Scratch Protection
■ Reliable, Multilayer Metalization with a Diffusion Barrier, 100% Stabilization Bake (300 °C, 16 hours)
■ Lower Susceptibility to ESD Damage
