PROBLEM TO BE SOLVED: To configure a small-sized directional coupler incorporating the dielectric line converter that is entirely made small while keeping a broadband characteristic and to obtain the dielectric line device using the dielectric line converter, the high frequency circuit module using the directional coupler or the dielectric line device and the transmitter-receiver. ;SOLUTION: A groove is formed to opposed faces of upper and lower conductor plates 1, 2, a dielectric strip 3 is placed in the groove, and an interval between conductor faces of a line conversion section TR is made narrower than an interval between conductor faces of a dielectric line HNRD of a 1st kind to match the impedance of the part TR with that of a dielectric loading waveguide DWG of a 2nd kind. Furthermore, the length L of the line conversion section is selected to be an odd number multiple of λg/4.;COPYRIGHT: (C)2000,JPO
