Abstract
A planar power combiner/divider device comprises a metallic layer on an insulating substrate. The metallic layer is configured to have an output (input) neck portion (12) which extends into a purely tapered portion (16) which in turn splits into n tapering conductors (1 to 5), the terminal portions of which constitute input (output) ports. The overall length (L) of the metallic layer between a junction (14) of the neck and purely tapering portions to each input (output) port being substantially constant and equal to substantially half the wavelength of the lowest design frequency and the distance x from the junction (14) to the (first) split into tapering conductors is selected so as to avoid transverse resonance at the desired frequencies.
