Active phased array transmitting-receiving component with high integration density

Abstract

The invention discloses an active phased array transmitting-receiving component with high integration density. The phased array transmitting-receiving component is small in volume and high in integration density, and is realized through the following technical schemes: a phased array T / R component and a comparator are integrated in a high-frequency printed board through vertically interconnected radio frequency printed boards so as to form a high-density phased array T / R component integrated with the comparator; the phased array T / R component modulates and synthesizes radio frequency signals transmitted from antennas through the vector when working in a receiving mode R, and the radio frequency signal vertical transition is performed through the vertically interconnected radio frequency printed boards, and vector overlapping is performed on input radio frequency signals through the comparator, so that the input radio frequency signals after the vector overlapping are transmitted to an end machine to use; the T / R component performs vector modulation and amplification on the radio frequency signal transmitted from the end machine through the comparator, the vertically interconnected radio frequency printed boards and the phased array T / R component, and the radio frequency signal after the vector modulation and amplification is transmitted to the antenna so as to be used as an excitation source.

Description

technical field [0001] The invention relates to a transceiver assembly mainly used in the field of aircraft data communication, in particular to a high-density active phased array transceiver assembly. [0002] technical background [0003] The active phased array transceiver T / R component is the core component of the active phased array radar system. The T / R component contains the receiving and transmitting links inside. The transmitting channel and the receiving channel are integrated in one component, sharing the phase shifter, Attenuators, RF switches and transmitting and receiving feed networks. In a typical phased-array radar system, each antenna radiating element is followed by a solid-state phased-array T / R component. Phased array T / R component technology, using the computer to control the state of each phase shifter, so as to control the component phase reaching each antenna radiating element, to change the radiation energy distribution of each radiating antenna ele...

Problems solved by technology

Such a design makes the module integration level low, the design is cumbersome, the volume of each module cascaded is large, the alignment requirements between the radio frequency interfaces are high, and the advantages of weight and cost cannot be highlighted, which is an important problem faced by phased array T / R components. question

[0005] To sum up, in the active phased array T / R component in the field of phased array radar, it is necessary to modularize the T / R component and the summator and package them separately. The component integration is low and the volume is large. This limits the miniaturization and low-cost application of the phased array transceiver system
