Abstract

PURPOSE:To miniaturize a device and to lighten in weight, by forming strip conductors which connect input/output terminals, respective coupling conductor of each directional coupler, between each terminal and each coupling conductor, and between the coupling conductors on two dielectric substrates of a ground conductor after bi-secting. CONSTITUTION:The titled device is constituted by forming two coupling conductors 51aa and 51ab in which end parts confronting with each other constitute the input/output terminals 1-4, and 5-8 in 2 directional couplers 50a-50d at both sides of the ground conductor 11 via the dielectric substrates 10a and 10b, respectively, and coupling electromagnetically between the coupling conductors 51aa and 51ab via a notched part provided at the ground conductor 11 being formed between the coupling conductors 51aa and 51ab. Therefore, it is possible to form the strip conductors 61-67 and 71-76 which connect the input terminals 1-4, the output terminals 5-8, the coupling conductors 51a and 51b of the directional couplers 50a-50d, between each terminal and the coupling conductors 51a and 51b, and between the coupling conductors 51a and 51b. Thereby, miniaturization can be realized.
