The present invention relates to optimization of communication equipment with respect to size and undesired signal interference. To this aim a ceramic feedthrough interconnection assembly is proposed in order to transport an electrical information signal to and from a communication capsule. In addition to at least one signal lead ( 103 a, 103 b) for communicating an electrical information signal, the assembly contains at least one auxiliary lead and a shield ( 103 c, 103 d, 104, 104 a, 104 b, 104 f) that electrically shields the at least one signal lead ( 103 a, 103 b) from the at least one auxiliary lead. The shield ( 103 c, 103 d, 104, 104 a, 104 b, 104 f) has such dimensions (d<SUB>1</SUB>, d<SUB>2</SUB>) and is positioned at such distance (d<SUB>3</SUB>, d<SUB>4</SUB>, d<SUB>12</SUB>) from the at least one signal lead ( 103 a, 103 b) that the electrical information signal experiences a well-defined and substantially constant impedance in the assembly. This in turn, minimizes the risk of undesired signal reflections. At the same time the assembly allows a high lead density, i.e. short distances between the leads. |
