ADI’s Technological Strengths

ADI is globally renowned for its advanced radio frequency (RF) technology, AD/DA converters (ADCs/DACs), and digital signal processors (DSPs). These chip solutions lead the industry in performance, stability, and energy efficiency. In the field of wireless digital audio, ADI’s RFAD2X series chips and related technologies provide strong support for audio developers.

ADI’s RF chips are known for their high sensitivity and low power consumption, effectively improving the quality and stability of wireless audio transmission. In addition, ADI’s AD/DA converters provide high-fidelity audio performance during signal processing, enabling end users to experience more realistic and refined sound. These technological advantages offer strong technical support for AMSaudio’s wireless microphone products, driving product iteration and upgrades.

AMSaudio’s Innovation Exploration

As an innovative enterprise focused on wireless audio technology, AMSaudio is committed to delivering outstanding audio experiences through advanced technologies. Its new-generation D Series wireless audio solution is designed to meet market demand for high-quality audio transmission. This product series not only delivers excellent sound performance but also optimizes usability and product design to meet diverse modern user needs.

Through its collaboration with ADI, AMSaudio combines its innovative concepts with ADI’s technological strengths to secure a strong position in the wireless digital audio market. During the technical exchange, both sides focused on how to effectively integrate ADI’s RFAD2X series chips into AMSaudio’s D Series solutions to address traditional technical challenges such as RF direct AD sampling and audio compression.

In-Depth Discussion of Core Technologies

During the exchange, ADI engineers and AMSaudio’s senior engineer Luo Wensheng held in-depth discussions covering key technical areas including chip architecture, software design, and logic control. Both sides examined issues in the core development boards, and ADI’s team provided targeted technical solutions to help AMSaudio address R&D challenges. For example, in RF direct AD sampling, ADI proposed a new sampling algorithm that effectively reduces signal processing latency, improving real-time wireless audio transmission. This enables users to enjoy smoother audio experiences in different scenarios. In audio compression, both parties discussed leveraging ADI’s DSP chips for more efficient encoding and decoding, improving transmission efficiency while maintaining sound quality and reducing bandwidth consumption.

Luo Wensheng proposed that a 10 GHz AD high-speed sampling rate could enable the D Series microphones to operate across global frequency ranges. This would significantly simplify analog circuitry by directly connecting ADC/DAC components to RF signals, with most correction, frequency conversion, and filtering tasks handled by digital circuits. FPGA technology specializes in digital processing, making this approach highly suitable. The RFAD2X series integrates RF ADC/DAC within FPGA, forming a streamlined architecture. ADC/DAC interfaces connect directly to external RF signals, while DDC/DUC (digital down conversion/up conversion, including digital filtering) are FPGA strengths. A single FPGA can integrate up to 16 transmit and 16 receive RF channels.

Shared Vision of Both Parties

This technical exchange marks a further deepening of cooperation between ADI and AMSaudio in the wireless digital audio field. Both sides reached alignment not only on technical matters but also discussed future strategic cooperation opportunities. ADI and AMSaudio look forward to driving technological innovation and achieving mutual success through close collaboration.

In future cooperation, ADI will continue providing technical support, while AMSaudio will apply ADI’s technologies to enhance product performance and market competitiveness. Their shared vision is to improve user audio experiences through continuous innovation and open broader prospects in the wireless audio market.

Conclusion

The development of wireless digital audio technology depends not on a single enterprise but on collaborative efforts across the industry. The cooperation between ADI and AMSaudio exemplifies this trend. Through technical exchange and collaboration, both parties aim to advance wireless digital audio technology so that more users can enjoy high-quality
