SDCD-POW-4 ABB输入/输出(MIMO)收发器

ABB模块SDCD-POW-4

多输入、多输出(MIMO)收发器架构广泛用于高功率RF无线通信系统的设计。作为迈入5G时代的一步，覆盖蜂窝频段的大规模MIMO系统目前正在城市地区进行部署，以满足用户对于高数据吞吐量和一系列新型业务的新兴需求。高度集成的单芯片射频收发器解决方案(例如，ADI新推出的ADRV9008/ADRV9009产品系列)的面市促成了此项成就。在此类系统的RF前端部分仍然需要实现类似的集成，意在降低功耗(以改善热管理)和缩减尺寸(以降低成本)，从而容纳更多的MIMO通道。

MIMO架构允许放宽对放大器和开关等构建模块的RF功率要求。然而，随着并行收发器通道数目的增加，外围电路的复杂性和功耗也相应升高。ADI采用硅技术的新型高功率开关专为简化RF前端设计而研发，兔除外围电路的需要并将功耗降至可忽略不计的水平。ADI采用硅技术的新型高功率开关为RF设计人员和系统架构师提供了提高其系统复杂度的灵活性，且不会让RF前端成为其设计瓶颈。

在时分双工(TDD)系统中，天线接口纳入了开关功能，以隔离和保护接收器输入免受发送信号功率的影响。该开关功能可直接在天线接口上使用(在功率相对较低的系统中)，或在接收路径中使用(针对较高功率应用），以保证正确接至双工器。在开关输出上设有一个并联支路将有助改善隔离性能。

Multiple input, Multiple output (MIMO) transceiver architecture is widely used in the design of high power RF wireless communication systems. As a step into the 5G era, massive MIMO systems covering cellular bands are currently being deployed in urban areas to meet the emerging needs of users for high data throughput and a range of new services. The launch of highly integrated single-chip RF transceiver solutions, such as ADI's new ADRV9008/ADRV9009 product family, contributed to this achievement. Similar integration is still needed on the RF front end of such systems, with the aim of reducing power consumption (to improve thermal management) and size (to reduce cost) to accommodate more MIMO channels.

The MIMO architecture allows for relaxation of RF power requirements for building blocks such as amplifiers and switches. However, as the number of parallel transceiver channels increases, so does the complexity and power consumption of the peripheral circuits. ADI's new high-power switch using silicon technology was developed specifically to simplify RF front-end design, eliminating the need for peripheral circuitry and reducing power consumption to negligible levels. ADI's new high-power switch based on silicon technology gives RF designers and system architects the flexibility to increase the complexity of their systems without making the RF front end a design bottleneck.

In time division duplex (TDD) systems, the antenna interface incorporates a switching function to isolate and protect the receiver input from the power of the transmitted signal. This switching function can be used either directly on the antenna interface (in relatively low power systems, as shown in Figure 1) or in the receiving path (for higher power applications) to ensure proper connection to the duplexer. Having a parallel branch on the switch output will help improve isolation performance.

The specific product application areas of the ABB SC610 digital input module depend on user needs and industrial application scenarios. It can be widely used in manufacturing, chemical, power, water treatment, transportation and other industries. Common application areas include:

1. Industrial production process monitoring: used to monitor various production processes in the manufacturing industry, such as temperature, pressure, flow and other parameters.

2. Power system monitoring: In the power generation and distribution system, it is used to monitor the status of power equipment, such as the speed, voltage and current of the generator.

3. Water treatment and sewage treatment: used to monitor water level, flow, concentration and other parameters in the water treatment and sewage treatment process. 4. Transportation and traffic: used in traffic signal control, railway signal system and other fields for traffic management and control.

5. Intelligent building: In the building automation system, used to control lighting, air conditioning, security and energy management and other equipment.
