摘要：【中文】本发明公开了一种高频开关型移相器，由5度移相单元、11度移相单元、22度移相单元、45度移相单元、90度移相单元构成，可以覆盖180度移相范围。所述的5度移相单元由开关电感移相结构实现，所述的11度移相单元、22度移相单元、45度移相单元、90度移相单元由优化T型移相结构实现。本发明提出了上述的开关电感移相结构和优化T型移相结构；基于该两种结构，进一步提出了移相单元的选取和排列策略，最终可实现低损耗、低移相附加衰减、宽带的移相效果。本发明为纯无源电路结构，无直流功耗，并支持正反双向移相；采用直接数字控制，相比基于数模转换(DAC)的模拟电压控制，具有时延低、反应快的优势。本发明适用于相控阵系统的移相器设计。 【EN】The invention discloses a high-frequency switch type phase shifter which is composed of a 5-degree phase shifting unit, an 11-degree phase shifting unit, a 22-degree phase shifting unit, a 45-degree phase shifting unit and a 90-degree phase shifting unit and can cover a 180-degree phase shifting range. The 5-degree phase shift unit is realized by a switched inductor phase shift structure, and the 11-degree phase shift unit, the 22-degree phase shift unit, the 45-degree phase shift unit and the 90-degree phase shift unit are realized by an optimized T-shaped phase shift structure. The invention provides the switch inductor phase shift structure and the optimized T-shaped phase shift structure; based on the two structures, selection and arrangement strategies of the phase shifting units are further provided, and finally, the phase shifting effects of low loss, low phase shifting additional attenuation and broadband can be realized. The invention is a pure passive circuit structure, has no direct current power consumption and supports positive and negative bidirectional phase shifting; compared with analog voltage control based on digital-to-analog conversion (DAC), the direct digital control has the advantages of low time delay and quick response. The phase shifter is suitable for designing the phase shifter of the phased array system.
