ADAPTER FROM WAVEGUIDE TO ELECTRON CIRCUIT, METHOD MINIMIZING SIGNAL LEAK FROM JUNCTION, WAVEGUIDE-SIGNAL CONDUCTOR AND ADAPTER OF PRINTED CIRCUIT BOARD TO MINIMIZE SIGNAL LEAKS Russian patent published in 1999 - IPC

FIELD: electronics. SUBSTANCE: proposed adapter for radio frequency waveguide signal minimizes leaks on radio frequencies thanks to origination of collection of through or blind holes with electrolytic coat in printed circuit board. Holes with coat are arranged over circumference which center is waveguide pin of unction " waveguide-microfilm line ". Each hole is linked to grounding plate. Size and relative position of holes with coat create barrier to leak of signals on radio frequencies in range of 10.95-11.70 GHz and provide for impedance value of junction close to characteristic impedance of 50.0 ohm line to ensure satisfactory matching and minimal leak into material of board. This adapter can also be used to minimize leaks in junctions " microfilm-microfilm " with transition through board. EFFECT: diminished losses of signals. 10 cl, 5 dwg
