摘要
In this paper, the design of coils inductively-tuned RF MEMS shunt switches using novel modeling method is presented. In this model, both lumped elements and coplanar waveguide (CPW) are used in the electrical equivalent circuit due to the fact that the up-state capacitance is usually very small, and the CPW loss is a main contribution to the up-state insertion loss. The CPW is estimated less than 0.2dB at 0-10GHz in most case. The modeling method allows us to simulate the RF switch more efficiently compare to that with the commercial FEM CAD tools. Using this model, optimized switches with tuning coils operation at S-band are obtained. The isolation of the switches is 23dB@4GHz and 16dB@2.4GHz respectively. The modeling results are verified by using HFSS simulation.
