RADIO-ELECTRONICS BLOCK Russian patent published in 2007 - IPC H05K1/00 H05K9/00 H05K3/46 

FIELD: the invention refers to radio-electronics.

SUBSTANCE: it may be used at constructing single-board radio-electronics blocks placing electro-radio-elements in the zones of analog and digital processing of signals connected between themselves by signal chains. The radio-electronics block has a multi-layer circuit board carrying printed conductors and electro-radio-elements grouped according to the zones of analog and digital processing of signals. The zones are screened with the aid of flat screens formed by situated in one of the inner conducting layers of terrestrial planes serving as conductors of feeding of the potential "Earth" for electro-radio-elements of their zones. The terrestrial planes are separated one from another with demarcation strip, deprived of metallization, passing along the frontier between the zones. The signal circuits between the zones are fulfilled with using of active buffer elements located in the inner conducting layer on the frontier between the zones. The configuration of the frontier line and spacing on it of active buffer elements is such that outlets "Earth" and "Feeding" and outlet signal outputs of the active buffer elements serving for transmission signals into the zone of analog processing signals and entrance signal outputs of the active buffer elements serving for transmission signals from the zone of analog processing of signals are in this zone and are connected with it correspondingly with its terrestrial plane, with the conductors of feeding of potential "Feeding", with inputs of electric circuits serving for reception of signals transmitted into this zone and with outputs of the electric chains serving for forming signals transmitted from this zone and the outputs of feeding "EARTH' and "Feeding" and outlet signal outputs of the active buffer elements serving for transmission of signals into the zone of digital processing of signals and entrance signal outputs of active buffer elements serving for transmission of signals from the zone of digital processing signals are in this zones and connected with it correspondingly with its earth plane, with conductors of feeding of the potential "Feeding", with inputs of electric circuits serving for reception of signals transmitted into the given zone and with the outputs of electric circuits serving for forming signals transmitted from this zone.

EFFECT: increases jamproof signal circuits.
