Abstract
The invention applies to packages for transmitting signals at very high frequencies. A package (10) for the integrated circuit (11) comprises conductors disposed on at least two levels (N1-N6) and distributed so that two pairs of conductors of two fixed potentials (18d, 18g; 19d, 19g), along with a conductor (18s) for single-pole transmission of a signal, form a three-dimensional structure which is approximately coaxial having a characteristic impedance which is substantially constant and predetermined.
