The MA4SW410B-1 device is a SP4T Series-Shunt Broad Band Switch with an Integrated Bias Network utilizing M/A-COM's 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 Ku Band frequencies.
