Abstract
The invention relates to a 90° power divider for distributing the power of an input signal (E) to two output branches (A1, A2) that are phase-shifted against each other by 90°. A capacity (C) is arranged in one output branch (A1) and an inductivity (L) is arranged in the remaining output branch (A2). Said capacity and inductivity are measured as follows: C=½*π*Z1*Fo, L=Z2/2*π*Fo, whereby Fo is the centre frequency and Z1 and Z2 are the terminating resistances of the output branches (A1, A2) respectively.

90° power divider for distributing the power of an input signal (E) to two output branches (A1, A2) phase-shifted against each other by 90°,
- characterised in that in one output branch (A1) a capacity C and in the other output branch (A2) an inductivity L is arranged, with dimensions as follows:
- C = 1 2 * π * Z 1 * Fo L = Z 2 2 * π * Fo
- wherein Fo is the centre frequency and Z1 and Z2 are in each case the terminating resistances of the output branches (A1, A2).
