Therefore, after all the electronic components are assembled on the board, the high frequency characteristics are adjusted by changing the constants of the electronic components, such as the inductance value of the air-core coil, while maintaining the high frequency characteristics to obtain the desired characteristics.

The inductance value of air-core coil b can be changed by crushing it diagonally as shown in Figure 5, and changing the inductance value of air-core coil b by changing the degree of crushing, or by partially widening the interval between adjacent wound conductors as shown in Figure 5.

なる等の課題があった。(Problem to be invented or solved) In air-core coil b, which has one turn or half a turn, in order to obtain a low inductance value, the inductance value does not change even if it is crushed diagonally as described above. Since it is not possible to widen the spacing between the wound conductors, each time the coil is replaced with another air-core coil to obtain the desired high-frequency characteristics. Therefore, there are problems in that it takes time and effort to adjust the characteristics of the high frequency circuit device, and the cost also increases.
