According to the reciprocal characteristic of dual - mcde reciprocal ferrite phase shifters, the antenna only requires to provide the sa : lle beams of operation between the trtinsmit and receive beams. in addition, 1he phased shifter can operate in various polarizations such as linear polarization or circular polarization, which is adiipted to the development of modern ra ( 1ar technologies
對電掃描相控陣天線來說,雙模互易式鐵氧體移相器的互易特性可使收、發在同一特定波束位置上工作;此外,雙模互易鐵氧體移相器可以在線極化、圓極化等多種極化方式下工作,適應了現代雷達技術的發展。 -
The basic operation principle of phase - locked frequency synthesizer and the type of circuits are expatiated systematicly in this paper. the principle of operation on sampling phase detector and some characteristics including the linear tracking and phase noise in phase loop circuits are analyzed deeply. the research is emphased on the theory and design method of circuits in the sampling phase - locked frequency synthesizer. then, the expansion capturing circuit is analyzed and designed for better performance of capturing loop circuits. at last, the loop filter is also analyzed and contrived taking account of effection of additional phase shift by the sampling - holder. the general research on the theory and technology of sampling phase lock in the paper will make a basement for the development of new product
