Phased array antenna refers to an antenna that changes the pattern shape by controlling the feed phase of the radiating units in the array antenna. It is an area array composed of a large number of identical radiating units. Each radiating unit is independently wave-controlled in phase and amplitude. and phase shifter control to obtain accurate and predictable radiation patterns for beam control and scanning. Phased array is mainly composed of three parts: antenna array element, wave control network and power divider. Its technology involves radio frequency transceiver system, amplifier, filter, phase shifter, power divider, antenna design, micro-assembly process, etc. Therefore, , phased array design technology can be called the "ceiling-level" technology in the microwave field.

Course Nature: "Radio Frequency Circuits and Antennas" is an important professional basic course for information engineering, electronic science and technology, integrated circuits and physical electronics. It is closely related to the modern electronic information industry, especially the wireless communications and mobile communications industries. However, these courses are classic traditional courses. How to enable undergraduates who do not have a strong foundation in mathematics and physics to learn these courses well and understand and master the knowledge and technologies most closely related to modern electronic information technology within a limited number of hours is an important task. A difficult problem facing these courses is a constrained optimization problem.

Successfully capturing signals with sufficient fidelity is a major challenge in communications system design. Of course, strict standards specifications will require the selection of an appropriate interface topology. In this webinar, we will explore the benefits of differential design techniques and how their performance advantages impact the stringent system requirements in today's high-performance communications systems. Additionally, we will review the definition of RF, outline system budgets, and compare different implementation approaches.
