Abstract
The invention concerns a 90-degrees hybrid coupler comprising two conductors 5, 6 separated from each other, the ends 5d, 5e, 6d, 6e of which form the inputs and outputs of the hybrid coupler. The conductors 5, 6 comprise three series-connected conductor sections 5a - 5c, 6a - 6c in which the electrical length of each is approximately a quarter of the wavelength for the average frequency of the hybrid coupler. To achieve the greatest possible total connection coefficient, the connection between the conductors is weakest at the middle section 5c, 6c of the hybrid's conductors. <IMAGE>
