Chinese chip manufacturers have launched the PIN TO PIN replacement chip for the RF transceiver chip AD9361

For a long time, ADI's AD9361 has been regarded as the "gold standard" in the field of software-defined radio and 4G/5G small base stations due to its high integration, wide frequency band coverage and reconfigurable features. However, supply chain risks and cost pressures have prompted the industry to urgently seek stable and reliable alternatives.

Typical application fields of RX9361 5G/4G small base stations and relay systems: Provide complete physical layer radio frequency transmission and reception support, suitable for low-cost, high-performance small base station deployments, FDD/TDD mode switching, and uplink/downlink diversity scenarios. Software-defined radio (SDR) platform: With highly flexible parameter configuration capabilities, it is an ideal hardware platform for protocol simulation, waveform research, and system development in scientific research institutions, universities, and military units. Industrial Wireless Control and Remote Operation System: In industrial environments with high interference and heavy loads, it achieves stable and low-latency communication, and is widely applied in intelligent factories, remote mechanical control, AGV systems, etc. UAV communication and satellite remote sensing link: Supports long-distance, low-power consumption, and high-speed image transmission, suitable for UAV remote control / video transmission links, small satellite ground terminals, and other scenarios. Internet of Things and Intelligent Edge Gateway: Capable of supporting wireless connections in multiple standards and frequency bands, meeting the ubiquitous connection requirements for smart water meters, urban sensing terminals, environmental monitoring, etc. High-definition video transmission link: The TRX9361 can achieve wireless low-latency transmission of 1080P and 4K videos, and is suitable for bandwidth-sensitive scenarios such as remote medical care, security monitoring, live video transmission, and drone video transmission. Point-to-point communication and satellite transmission: In microwave transmission and satellite communication, the TRX9361 ensures a reliable link with long distance and low bit error rate through a high linearity transmitter (EVM less than or equal to -40dB) and a low noise receiver (NF < 2.5dB). Broadcast and Test Measurement: In ADS-B systems or radio test platforms, multiple target RF signals can be simulated for aviation radar interleaving verification. It can also be used as a broadcast repeater to receive, modulate, and retransmit FM signals (87-108 MHz).

Trends and Development Opportunities in the High-Performance RF Transceiver Chip Market As emerging scenarios such as new infrastructure, vehicle networking, industrial internet, low-orbit satellite communication, and smart cities increasingly rely on wireless communication, higher requirements have been imposed on the performance, flexibility, and domestic production rate of RF chips. With its highly integrated design, flexible configuration and local support capabilities, TRX9361 is becoming one of the key components for future multi-scenario wireless communication solutions. TRX9361 is not only an alternative chip compatible with AD9361, but also a manifestation of Xindong Zhongguo's comprehensive mastery and innovation of RF communication core technologies. We believe that in the new era where intelligence and wirelessization are deeply integrated, TRX9361 will help more enterprises build stronger competitive wireless communication systems, and jointly reach a new height of "domestic substitution".
