High power 6-18 GHz transfer switch using HMIC

Methods of using commercial electromagnetic simulators for microwave and millimeter-wave circuit design and optimization

“…Thus, when and are reverse biased and and forward biased, the signal from terminal 1 goes to terminal 3 while the signal from 2 is terminated in a high-power AlN resistor. The through path as well as the terminating path are simultaneously implemented as asymmetric commensurate line filters modified by capacitive loading [10], [11]. For the through path there is a shunt stub followed by two series quarter-wave sections and then a shunt stub followed by another series section and a bias return shunt stub.…”

“…The limiter diodes were not implemented in HMIC as the optimum I-region thickness required by the two limiter diodes are different from each other and from that of the integrated switch diodes -. The diodes have nonzero capacitance, which is incorporated in the filter using standard techniques [10], [11]. Fig.…”
