Capacitor가 결합된 3-dB Branch-Line Hybrid Coupler에 관한 연구
金炳哲,李永淳 金烏工科大學校 1988 論文集 Vol.9 No.-
Design and analysis techniques are presented for 3-dB branch-line hybrid coupler with the capacitor for MIC/MMIC applications. The circuit area is reduced to less than 25 percent of conventional transmission line realization at 830 MHz. Test results are presented for a 3-dB coupler, Good agreement is obtained between measured and modeled results.
