PURPOSE:To improve the impedance characteristics when viewed from the input terminal by connecting N-units of the single amplifier containing the phase shifters featuring the sequential change of the phase shift amount by 180/N at the front and rear parts each between N-units of terminals of two units on N-division in-phase hybrids. CONSTITUTION:The input signal given through terminal 21 is divided into three parts by 3-division in-phase hybrid 23. The divided 1st, 2nd and 3rd output signals are supplied to each input terminal of 3-division in-phase hybrid 25 via direct single amplifier 23 and 120-phase shifter 24; 60-phase shifter 26, single amplifier 27 and 60-phase shifter 28; and 120-phase shifter 29 and single amplifier 30 respectively. Single amplifiers 23, 27 and 30 are equivalent to each other. Accordingly, the signals of each panel path are compounded in the same phase to the traveling wave, and the reflected waves are compounded and offset never to emerge at the input terminal. |
