Abstract

PURPOSE:To set a Qo higher at the time of applying no load and to increase a QL value at the time of applying the load by winding conductor width gradually in the neighborhood of the current short-circuit point of a strip line, to reduce radiation loss and conductor loss in a coupling tap. CONSTITUTION:The strip line 3 is constituted in such a way that the line length of the strip line 3 is set equivalent to the integer times (nlambdag/4) the 1/4-wave and the conductor width in the neighborhood of the current short-circuit point is widened gradually. Therefore, the radiation loss and the conductor loss in the coupling tap 5 of an oscillation transistor 1 with the coupling tap 4 or a variable capacitive diode 2 can be reduced, and the Qo of a Q at the time of applying no load on a strip line resonator can be increased. In such a way, the QL of the Q at the time of applying the load can be increased.
