Abstract

The present invention relates to a shielded electronic circuit for radio-frequency signals. The shielded electronic circuit for radio-frequency signals comprises, on a support (1), a cell (5) disposed above an earth plane (8) and covered with a metal cap (6). In addition, the support comprises a pattern feature (7) to which this cap is applied and a ring of holes (10) which are covered with an electrically conductive material connecting this pattern feature to the earth plane. The cell (5) comprises a power module (16) and the support (1) comprises an exchange surface (17), to which this power module is attached, which extends as far as the pattern feature (7). <IMAGE>
