Abstract
A passive limiter formed as a wave-guide, in at least one cross-section of the guide, by means of one or more resonating windows in which is shunt-mounted at least head-to-tail one pair of diodes having the same polarity and being disposed in the same plane. One or more such limiters may be contemplated for forming duplexers.
Claims19
A passive semi-conductor electromagnetic wave limiter with low capacity and high cut-off frequency, comprising a wave guide and at least a pair of diodes of same polarity mounted oppositely in shunt connection in said wave guide, the improvements comprising at least a resonant window arranged in a cross-section plane of said wave guide in which said pair of diodes of same polarity and oppositely mounted in shunt, are connected between the edges of said window in the same plane.
A passive semi-conductor electromagnetic wave limiter as claimed in claim 14, wherein the shape of the window, is modified at places where said diodes are arranged, by reducing the height of said window perpendicular to the longitudinal axis of said cross-section for forming a narrowed portion resulting in a reduction of the inductance of wires connecting said diodes to the edges of said window.
