MEMS Varactor Delay Line Arrays for Millimeter-Wave Beam Steering/Shaping s sLline sCline s Fabrication Process Objectives: Key Innovations: 1. RF-MEMS extended tuning range varactor design, compatible with MEMS Exchange process modules • Develop RF-MEMS extended tuning range varactors • Fabricate RF-MEMS varactor loaded delay lines for mm-wave phased antenna arrays (PAAs) 2. Shunt varactor layout compatible with use in coplanar waveguide (CPW) transmission lines CVaractor RF-MEMS Extended Tuning Range Varactor Layout • Expected Impact: • Incorporate extended tuning range RF-MEMS varactors into list of “standard” devices that can be fabricated using the MEMS Exchange • Open up field of low cost mm-wave PAAs Microscope picture: Before Electro-Plating
