Constant Impedance Switch

摘要

A constant impedance switch dynamically manages switch impedance to eliminate or substantially reduce impedance glitches during switching events by stepping variable impedances through sequences of impedance values. As a result, VSWR may be reduced to or near 1:1, allowing programming and circuitry to be simplified. Switch impedance may be maintained for single and multi-throw switches having variable impedances of any order. Each variable impedance may comprise one or more configurable cells, subcells and elements controlled by thermometer, binary, hybrid or other coding technique.
