Problems solved by technology

Although the miniaturization of the ADS-B system can be achieved through compact structure layout and appropriate integrated circuit synthesis technology, the effect of this method is limited. Even if the cost factor is not considered, it is completely dependent on high-performance small package components. It is also unable to meet the installation requirements of general aviation aircraft, especially the rapid development of unmanned aerial vehicles.

Abstract

The invention discloses an integrated radio-frequency ADS-B chip comprising an analog circuit part and a digital circuit part. The analog circuit part consists of a radio-frequency transmitting module, a radio-frequency receiving module and a transceiving switch. The digital circuit part includes an ADC module, a DAC module, a 1090ES interface module, a signal encoding and decoding module, a CPR and data encoding and decoding module and a data flow control module that are connected to a high-speed bus. According to the invention, with the semiconductor process integration technology, the analog radio-frequency 1090ES data link module in ADS-B system equipment, a logic control module, a signal processing module, an ADS-B protocol processing module, a GNSS interface module, a memory module,an ADC / DAC front-end module, and a power supply and power management module in the digital circuit are integrated into a single special integrated chip, so that miniaturization and low power consumption of the ADS-B system equipment are realized and thus integration of various functions of monitoring broadcasting, receiving processing, and display control and the like is realized.

Description

technical field [0001] The invention relates to an integrated circuit technology in the field of aviation technology, in particular to a special chip for realizing the ADS-B function. Background technique [0002] Traditional portable ADS-B terminal systems often consist of a series of discrete devices such as central processing modules (including GNSS modules, signal processing modules, S-mode and ADS-B protocol processing modules, etc.), transmitting modules, receiving modules, and power modules. The central processing module composes the navigation information of the machine into ADS-B information and sends it to the transmitting module for external transmission, and completes the ADS-B OUT function; decodes and analyzes the ADS-B information sent by the receiving module, and converts the resolved ADS -B information and the navigation information of the machine are output to the back-end device to complete the ADS-B IN function; the power module uses a built-in rechargeab...
