A New mm-Wave Multiple-Band Single-Pole Multiple-Throw Switch With Variable Transmission Lines

This article a new multiple-band single-pole N-throw (SPNT) switch topology suitable for mm-wave applications. Compared to a conventional shunt-type SPNT switch, the proposed SPNT operates in the multiple frequency bands by adopting a variable transmission-line (T-line) structure. The variable T-line (VTL) structure consists of multiple sections of T-line and multiple shunt switches. Therefore, it realizes a variable quarter-wave line at...
