branch line coupler
解釋
分支線耦合器-
Five cell circuits are designed, fabricated and tested, including 5. 625 degree and 45 degree using loaded - line phase shifter, 90 degree using 3db branch - line coupler phase shifter, 90 degree and 180 degree using switched - line with loaded - line phase shifter. according to the testing result of cell circuits, and requirement of ku - band six - bit digital phase shifter, the scheme for ku - band six - bit digital phase shifter is chosen
本文對5 . 625度和45度相移位採用主線加載的加載線形式,對90度相移位採用3db支線耦合器形式和加載式的開關線形式,對180度相移位採用加載式的開關線形式,分別進行了五個單元電路的設計、製作與測試。
