How to Select Aurasemi Wireless Transceivers
This technical reference document provides detailed information about aurasemi product specifications, characteristics, and performance parameters. Use this information to support your design and analysis activities.
Electrical characteristics are specified over the operating temperature range unless otherwise noted. Parameters are guaranteed by design, testing, or statistical analysis. Typical values is the most likely parametric norm at 25°C.
Thermal characteristics require careful attention during system design. The junction-to-ambient thermal resistance depends on the mounting configuration, PCB copper area, and airflow conditions. Use thermal simulation tools to predict operating temperatures under actual conditions.
Reliability data is based on accelerated life testing and field failure analysis. Mean time between failures (MTBF) calculations follow industry-standard methodologies. Contact BeiLuo for detailed reliability reports and qualification data.

Frequently Asked Questions
1. Should I use sub-GHz or 2.4GHz for my application?
Choose frequency band based on application requirements: (1) Sub-GHz (433/868/915MHz) - longer range, better penetration, lower power, but regional restrictions; (2) 2.4GHz - worldwide availability, higher data rates, more crowded spectrum. For long-range IoT sensors, sub-GHz is typically preferred. For consumer devices requiring global compatibility, 2.4GHz may be better.
2. Where can I find the latest datasheet?
The latest datasheets are available on the LiTong website in the product pages. You can also contact LiTong sales or FAE team to request the most recent documentation. Always use the latest revision for new designs.
3. How do I request technical support?
LiTong provides multiple channels for technical support: (1) Contact your local FAE directly; (2) Email technical support at support@litong.com; (3) Call the technical hotline; (4) Submit a support request through the website. For complex design questions, schedule a meeting with our FAE team. We typically respond within 24 hours.
4. Are evaluation boards available?
Yes, evaluation boards are available for most Aurasemi products. Contact LiTong sales to request evaluation boards for your application. Boards include complete documentation, schematics, and example software. Evaluation boards are typically provided free of charge to qualified customers.
