Abstract (en)

[origin: US4542358A] Device protecting a coaxial cable against high-powered low-frequency spurious pulses. A lightweight, compact device comprising a microstrip T-junction (5) folded back in the shape of an E on a substrate (6) integral to a single ground plate (7), with the branches of the E between the center point A and the coaxial plugs (1, 2) forming a quarter wavelength, as does the center horizontal branch of the E between points A and B. According to one of the variants, two microstrips arranged in parallel and separated by a dielectric substrate establish a quarter-wave trap. Application to microstrip resonant circuits.
