On November 25,2025, Corebai Microelectronics (Beijing) Co., Ltd. successfully concluded its "Core with Chips, Smartly Connecting the World – CBMRF9002/9009 Domestic RF Chip Launch Event" through a live-streamed event. This initiative, focusing on the localization of core components in communication infrastructure, attracted over 200 participants including 5G base station manufacturers, satellite communication companies, private network equipment providers, and industry chain partners. More than 30 enterprises submitted sample applications on-site, demonstrating the industry's high recognition of domestic RF chips' substitution capability in critical fields.

The press conference spotlighted the localization and cost-efficiency optimization of domestic RF chips. Through technical analysis, policy updates, and interactive Q&A sessions, it showcased the CBMRF900 series RF chips' outstanding performance and industrial value. The event concluded successfully with a series of highlights.

With years of expertise in developing and selling high-performance, high-quality ADC/DAC analog signal chain chips, Corebai Microelectronics upholds its core values of "Specialized Chip Development, Service-Oriented Chip Solutions, and Innovative Chip Future." The company is committed to delivering premium chip solutions for diverse sectors including industrial control, communication equipment, medical devices, and new energy vehicles. The newly launched CBMRF900 series, positioned as the flagship product under Corebai Microelectronics 'strategic layout, represents a groundbreaking achievement in the company's RF chip domain. This milestone signifies Corebai Microelectronics' critical breakthrough in the domestic development of RF transceivers.

At the press conference, R&D Technology Director Li conducted an in-depth disassembly of the two core products, CBMRF9009 and CBMRF9002. Among them, the CBMRF9009, as a highly integrated direct frequency conversion RF transceiver chip, boasts powerful configurations with dual transmitters, dual receivers, and dual observation receivers. It covers a carrier frequency range from 75MHz to 6000 MHz, with a maximum transmit bandwidth of 450MHz and a receive bandwidth of 400 MHz. With advantages such as the 12.288Gbps JESD204B interface, phase synchronization deviation of ≤±5des, and low phase noise of-126.7dBc/Hz, it outperforms similar overseas products in bandwidth support, startup speed, and phase synchronization. It can be widely applied in scenarios such as 4G/5G base stations, active antenna systems, and large-scale MIMO systems.

The flagship product CBMRF9002 demonstrates enhanced compatibility with an expanded carrier frequency range of 10MHz to 7250MHz, supporting simultaneous 4-channel frequency division operation and a maximum signal bandwidth of 100MHz. Featuring an integrated multi-chip phase synchronization mechanism and low-power monitoring mode, this 12mm×12mm CSP_BGA package meets diverse requirements including VHF/UHF communication systems, phased array systems, and testing equipment. Compared to overseas counterparts, its wider frequency range, faster startup speed, and superior output power highlight significant advantages in domestic substitution. To facilitate efficient development, Corebai Micro provides comprehensive support for both products, including FPGA-compatible subcards, API code, and detailed design documentation to accelerate product deployment.

Beyond showcasing cutting-edge technology, Sales Director Nana unveiled a series of sincere commercial collaboration policies at the launch event. For end customers, Corebaiwei has opened a free sample application channel with online technical support, enabling cost-free performance evaluations. To ensure supply reliability, the company has established a triple guarantee system featuring "instant sample delivery, on-demand mass production, and 6-8 week standard cycles," addressing material supply concerns comprehensively. Additionally, a special 9.2% discount code was introduced as a promotional benefit. These policies—combining "zero-threshold testing, stable supply, and high-value procurement" —directly tackle corporate pain points like "high trial-and-error costs, unstable supply chains, and tight procurement budgets," serving as the "cooperation catalyst" for this live event.

The successful launch of the CBMRF900 series RF chips not only demonstrates Corebaiwei's profound technical expertise in the field of analog signal chain chips, but also breaks the market monopoly of overseas products in this sector, providing the domestic communication industry with a new choice of "technically reliable, performance-stable, and cost-optimized" domestic solutions. In the future, Corebaiwei will continue to drive innovation through technological advancement, delve deeper into chip R&D, and constantly introduce more high-quality products that meet industry demands. Together with its partners, the company will jointly promote the high-quality development of China's integrated circuit industry, injecting strong momentum into the construction of a smart society through chips.

Corebaiwei will later release technical deconstruction reports and highlights from the launch event on its official platform. Companies not participating in the live stream can download materials or contact customer service via the website to apply for samples and exclusive procurement benefits.
