  • Abstract
    This abstract describes an improved manufacturing technology for fabrication of RF-MEMS switches on PCB. The 17.5 μm thick copper layer is patterned and planarized using polyimide. The use of polyimide reduces formation of voids in sacrificial photoresist. Fabricated switches demonstrate low insertion-loss (<0.06 dB at 10 GHz) and good isolation (>20 dB at 10 GHz).
