摘要

主题和目的。用于控制无线电信号相位的移相器广泛应用于超高频技术、通信系统、雷达以及各种测量和专用无线电设备中。相控阵天线的设计者面临着提供宽波束扫描角和高天线增益的需求,这就需要大幅增加阵列元素的数量,而每个阵列元素都需要由移相器控制。因此,开发和制造速效移相器是一项紧迫的任务。这项工作的目的是开发高速、可控的移相器,用于进行相角调整,从而以可接受的成本为相控天线阵列、磁控管稳频系统等提供理想的参数。方法和方法论。对所提出的速效可控移相器的功能图进行了数学分析和数值模拟。结果。通过在特定接收器的输入端使用两个并联谐振器,可以成功地实现可控移相器。对移相器输出端的信号幅度和相位与输入端的值的关系进行分析,证实了在大范围内调整输出信号相位的可能性。结论。提出了一种用于产生可调相角的速效、可控移相器的设计概念。该装置可用于相控天线阵列或频率稳定系统,作为改善其操作参数和降低其成本的手段。

QUICK-ACTING, CONTROLLABLE PHASE SHIFTER FOR PHASE ANGLE ADJUSTMENT IN RADIO SIGNALS
Subject and Purpose. The phase shifters intended for controlling the phase of radio signals are widely used in ultra-high frequency technology, communication systems, radar, and a variety of measuring and special-purpose radio equipment. Designers of phased array antennas face the need of providing for broad beam scanning angles and high antenna gains, which leads to the necessity of greatly increasing the number of array elements, each of which is to be controlled by a phase shifter. Therefore, the development and creation of quick-acting phase shifters is an urgent task. The purpose of this work is to develop high-speed, controllable phase shifters for performing phase angle adjustments and thus provide, at an acceptable cost, for desirable parameters of phased antenna arrays, frequency stabilizing systems of magnetrons, etc. Methods and Methodology. The functional diagram of the proposed quick-acting, controllable phase shifter has been analyzed mathematically and modelled numerically. Results. The controllable phase shifter can be successfully implemented through the use of two parallel-connected resonators at the input of a specific receiver. Analysis of the signal amplitude and phase at the output of the phase shifter in dependence on the values at the input confirms the possibility of adjusting the phase of the output signal over a wide range of angles. Conclusions. A design concept of quick-acting, controllable phase shifters for producing adjustable phase angles has been developed. The device can be employed in phased antenna arrays or frequency stabilizing systems as a means of improving their operation parameters and reducing their cost at that.
