Изобретение относитс к радиотехнике и может использоватьс дл уп-. равлени фазой СВЧ-колебаний в антенных репгетках и системах передачи информации. Цель изобретенид,..гг увеличение рабочей мощностии повьппение разв зки. W На 4e Tjeeic зображё1Н .предлагаемый СВЧ фазовращат ел. ь1 j ( СВЧ фазовр щатель сЬдержит экрани . L. -.t .

СВЧ-фазовращатель работает следующим образом. Между экранирующим 1 и центральны 4 проводниками возбуждаетс СВЧ-коле бание, которое распростран етс в ди электрической подложке 3 и сегнетоэлектрической пленке 2. Фаза СВЧ-колебани зависит от диэлектрической проницаемости сегнетоэлектрической пленки 2, котора , в свою очередь, зависит от напр женности электрического пол в параллельных и равных щел х 5, раздел ющих экранирующий проводник 1 на отдельные полоски. Прикладыва к этим полоскам управл ющее напр жение с измененной величиной, л U «. осуществл ют изменение фазой СВЧ-колебани . Так какщшна параллельных и равных щелей 5 значительно больше ширины центрального проводника 4, это способствует увеличению площади сегнетоэлектрической пленки 2 и, следовательно , рабочей мощности, а также уменьшению уровн СВЧ-колебани , просачивающегос в цепь источника управ-; т.е. способству л ющего напр жени , повьш ению разв зки.The invention relates to radio engineering and can be used for up. the phase of the microwave oscillations in the antenna repetkah and information transfer systems. The purpose of the invention, .. yy increase the working power and the opening of the exit. W At 4e Tjeeic image 1H. The proposed microwave phase-shift ate. j1 (microwave phase shifter holds screening. L. -.t. J, Jk. rup; .npoBp Aif i transmission linsh, ferroelectr. carrying film 2, dielectric cable 3, central guide 4 transmission lines, pa - parallel and equal gaps 5. The microwave phase shifter operates as follows: A microwave oscillation is excited between the shielding 1 and the central 4 conductors, which propagates in the dielectric substrate 3 and the ferroelectric film 2. The phase of the microwave oscillation depends on the dielectric constant of the ferroelectric film 2, which in turn depends t from the intensity of the electric field in parallel and equal slots 5, dividing the shielding conductor 1 into separate strips. Applying to these strips a control voltage with a changed value, l U U "., changes the phase of the microwave oscillation. Since the parallel and equal slots 5 are significantly greater than the width of the center conductor 4, this contributes to an increase in the area of the ferroelectric film 2 and, consequently, the working power, as well as a decrease in the level of the microwave oscillations flowing into the circuit of the control source; those. contributing to better stress, increased unraveling.
