The benefit of a T-switch over a transfer switch is that up to three combinations of RF paths are available, which is perfectly suited for space applications where more than two path combinations (DPDT) are required. In addition to superior RF performance and light
weight/high power capabilities, Dow-Key distinguishes itself from others by introducing random drive (minimizing the switching time) rather than forcing the application to switch RF paths in sequential order. These RF switches have been qualified in programs including MUOS (space craft), Isro (Indian Space program), and Insat-3 (multipurpose satellite design providing telecommunications, television broadcasting, meteorological, search and rescue services).
