Description
1. Overview of Satellite data Link.
Satellite communication is one of the important applications of satellite Internet, which mainly refers to data communication through or with the aid of satellite, which can be widely used in mobile users, remote operation, and related frontier applications. The satellite communications industry chain mainly covers infrastructure construction such as satellite manufacturing, delivery and launch and ground equipment, as well as operational services.
The commercial space satellite market * (mainly low-cost low-Earth orbit satellites) is expanding rapidly and has now become the driving force of market development, in contrast to geosynchronous orbit (GEO) satellites with many limitations, high cost and high altitude. With the emergence of these market changes, one of the main problems is how much radiation reinforcement is needed. Today, large quantities of commercial aerospace markets cannot afford "traditional" chips, components and equipment that are costly, demanding, radiation-resistant and meet aerospace standards, and are usually not needed.
The satellite data link based on 1G bandwidth is the core technology of 6G mobile communication in the future. The radio frequency transceiver platform based on AD9988 of ADI Company perfectly solves the communication problem of Sub-6G. Based on Transceiver, it can expand the frequency to X, KA. KU band. The following first explain the KA band satellite communication solution. Using AD9986 receiver and transmitter satellite communication system, the whole scheme Sub-6G module can be fixed, only need to switch the RF front end to achieve spread spectrum communication in different frequency bands.
The program promotes the development of commercial aerospace satellite industry.
Lower launch cost.
A spacecraft that is smaller, lighter and cheaper.
Demand for modern IC technology and new features.
Attention to low-Earth orbit missions and larger satellite clusters.
Need to shorten time to market.

2.1. Product details.
The user Guide describes AD9081-FMCA-EBZ, AD9082-FMCA-EBZ, AD9986-FMCB-EBZ, and AD9988-FMCB-EBZ evaluation cards, which provide all the support circuits needed to operate AD9081, AD9082, AD9986, AD9988, AD9207, AD9209, or AD9177 in various modes and configurations. The application software used to interface with the suite is also introduced. These evaluation cards are connected to ADI's ADS9-V2EBZ for evaluation using the ACE software.
The evaluation card can also be connected to commercially available field programmable gate array (FPGA) development cards from Xilinx ®or Intel ®. The "use of AD-FMC-SDCARD" section provides information on how to use these platforms to evaluate AD9081 or AD9082.
ACE software allows users to set up MxFE ®in a variety of modes to capture analog-to-digital converter (ADC) data for analysis. The DPGDownloaderLite software (included in the ACE installation) generates vectors and transmits them to a digital-to-analog converter (DAC), which can then be sent to a spectrum analyzer for further analysis. For more information, please refer to the AD9081, AD9082, AD9986, AD9988, AD9207, AD9209 or AD9177 data manual and UG-1578 (kit user guide), which must also be referenced when using the evaluation card.
