The MA4SW510B-1 is a SP5T Series-Shunt broad band switch with integrated bias networks made with 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 low loss glass. By using small spacing between elements, this combination of silicon and glass gives HMIC devices low loss and high isolation performance through 18 GHz.
