RADIOELECTRONIC BLOCK WITH IN-BOARD SCREENING Russian patent published in 2005 - IPC

FIELD: radio communications.

SUBSTANCE: device has multilayer electronic board with outer and inner conductive layers, carrying printed conductors and electric radio-elements, grouped in functional zones screened by barrier and planar screens. Functional zones are connected to power points positioned beyond their borders by appropriate two-conductor power feeds, consisting of couples of printed conductors Power and Ground, while inside the functional zone printed conductor Power of power feed is connected to appropriate filtering element, and printed conductor Ground - to ground plane, while functional zones are surrounded along their perimeters by individual barrier screens, constructively not connected to ground planes and connected to point of attachment of Ground potential on multilayer printed board by own ground printed conductors.

EFFECT: electromagnetically compatible different functional zones, including the case, when each one of them has common boundary with more than one other functional zone.
