FIELD: electricity. ^ SUBSTANCE: circuit module is mounted with an integrating circuit, which modulates and demodulates a signal with several carriers. The circuit module has a multilayer circuit board, which is equipped with multiple conducting layers inside laid with insulating layers between them, and the integrating circuit, which is equipped with multiple grounding outputs, which are to be grounded. From multiple conducting layers a conducting layer, which is closest to the integrating circuit, forms a grounding layer, which is electrically connected with multiple grounding outlets. ^ EFFECT: increased reliability and protection against noise. ^ 16 cl, 39 dwg |
