Abstract

PURPOSE:To make the size small and to give an excellent directivity, by providing a main line and a coupling line in parallel and making the length between the main line and the coupling line as <=1/8 than the frequency wavelength. CONSTITUTION:One electrode of an input power supply 1 is grounded, another electrode is connected to an input terminal 1 via a terminating resistor 51, and this input terminal 1 is connected to an output terminal 4 via a main line 7. The output terminal 4 is grounded via a terminating resistor 53. Further, one end of a coupling line 8 is connected to a coupling terminal 2, which is grounded via a terminating resistor 52. Another end of the coupling line 8 is connected to a noncoupling terminal 3, which is grounded via a terminating resistor 54. The length between the main line 7 and the coupling line 28 is taken as <=1/8 of the frequency wavelength lambdag. The A shows the passage loss from the input terminal 1 to the output terminal 4, the B indicates the coupling degree and the C shows the directivity.
