The MA4SW410 is a SP4T Series-Shunt Broad Band Switch made with M/A-COM's Unique HMICTM (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.
