The MA4SW510 is a SP5T Series-Shunt broad band switch made with M/A-COM's HMIC TM (Heterolithic Microwave Integrated Circuit) process, US Patent 5,268,310. This process allows the incorporation of silicon pedestals that form series and shunt diodes or vias by imbedding them in a low loss, low dispersion glass. This hybrid combination of Silicon and Glass gives HMIC Switches exceptional low loss and remarkable high isolation through low millimeter-wave frequencies.
