PROBLEM TO BE SOLVED: To provide a high frequency device which acquires branch signals, the frequency dependence of which is small over a wide band. SOLUTION: The high frequency device has a directional coupler in which some part of a main line 1 and some part of a branch line 2 are electromagnetically coupled, and a frequency corrector (an attenuator 4 and an equalizer 5) which corrects the frequency characteristics of high frequency signals over a specified wide band, which are extracted from some part of the main line 1 by the directional coupler and transmitted from some part of the branch line 2, so as to reduce the frequency dependence over the specified wide band.
