As proven a week ago by my definition quotations from "The IEEE Dictionary". I shall not try to pop the bubble of your glory in the triumph of knowing the correct terminology. But I still shy away from matching impedances with a "choke". I would match impedances with a balun or RF transformer. Jerry Sevick, W2FMI, says a *balun IS a choke* plus a transmission line. He wrote in "Building and Using Baluns and Ununs": "If the writers had accepted the correct model for these devices (given to us by Guanella and Ruthroff), which shows that *they are really chokes* (lumped elements) and configurations of transmission lines (distributed elements), ..." (emphasis mine) -- 73, Cecil *http://www.w5dxp.com The lumped element equivalent of the transmission line itself is a repetitive pattern of inductors and capacitors. If all inductors are chokes, then the transmission line itself is composed of chokes. |
