Circuit board for HF circuit, esp. amplifier - has large conducting earthed areas, from which functional units are separated by lines of holes

摘要

The circuit board carries HF components, and has on both sides large earthed conducting areas outside the conducting traces typically of copper. They are connected with each other at several points. At least one functional unit provided on the board board (2) is separated on at least one side (9-8, 1-1) from the conducting areas by holes (5) arranged in lines, whose dia. is greater than the width of existing connections, with metallised inner sides. The circuit arrangements include special earth connectors and bridge pieces if the skin effect prevails.
