PURPOSE:To realize the microwave circuit the size of which does not call for forming its pattern again and in which the size of the circuit pattern and the component mount point are revised for the adjustment of the circuit characteristic with respect to the microwave circuit connecting to a main line being the microstrip line and having the circuit pattern giving an additional function such as a filter and an attenuator. CONSTITUTION:Only a pattern 2 is provided to other sub board 20 than a board 10 of a main line 1 in the microwave circuit having the circuit pattern connecting to the main line of the microstrip line and giving an additional function and the circuit pattern 2 of the sub board 20 is mounted onto the main line 1 of the sub board 20 opposite to the main line 1. Furthermore, part of the main line is cut off so that the function to be added to the main line is not lost when the circuit pattern 2 of the sub board 20 is opposite to the main line 1. |
