As global 5G network construction moves from large-scale deployment to deep coverage, the demand of 5G infrastructure for chips is shifting from “quantity” to “quality.” According to GSA statistics, as of Q1 2026, more than 130 countries have deployed commercial 5G networks, the total number of base stations has surpassed 3.5 million, and 5G connected users exceed 1.8 billion.
The impact of 5G on the chip industry goes far beyond the base-station equipment itself. From RF front-end to baseband processing, from optical modules to edge computing, 5G is reshaping the value distribution across the entire semiconductor supply chain. The RF front-end chip market is expected to reach $35 billion in 2026, with 5G-related share exceeding 60%.

Base-Station RF Chips: Domestic Substitution Accelerates
5G base-station RF front-ends need to support both Sub-6GHz and mmWave bands, placing higher demands on the performance and integration of components such as PA (power amplifier), LNA (low-noise amplifier), filters, and switches. Domestic RF chip companies have achieved mass-production breakthroughs in the Sub-6GHz PA field, and the performance gap with international giants for vendors such as Vanchip and Fortior is steadily narrowing.
In the mmWave band, due to higher process requirements and design difficulty, international vendors such as Qorvo, Skyworks, and Murata still dominate. However, domestic vendors have made progress in 28nm CMOS RF chips and are expected to achieve initial substitution of mmWave RF front-ends by 2027.
Optical Module Chips: The Speed Race Heats Up
The demand for optical module speeds in 5G fronthaul, midhaul, and backhaul is rapidly evolving from 25G to 50G, 100G, and even 400G. The core chips inside optical modules – laser driver ICs, TIAs (transimpedance amplifiers), and DSPs (digital signal processors) – have become the focal point of competition. Domestic optical chip companies have achieved mass production of 25G and 50G DFB/EML laser chips, while 100G products are in the validation stage.
Silicon photonics technology is changing the manufacturing paradigm of optical modules. Intel, Marvell, Cisco, and others have introduced CPO solutions integrating silicon photonics engines, co-packaging photonic devices with electronic chips to significantly reduce power and cost. The domestic silicon photonics supply chain is gradually maturing in areas such as coupling packaging and waveguide design, and SMIC’s silicon photonics process platform already supports mass production.
Edge AI Chips: Deep 5G + AI Convergence
5G networks provide a low-latency, high-bandwidth transmission channel for edge AI inference, giving rise to huge demand for edge AI chips. From visual inspection in smart factories to real-time decision-making in autonomous driving, edge AI chips must balance compute, power, and cost. Domestic edge AI chips from Rockchip, Allwinner, and others have been deployed at scale in scenarios such as security and industrial vision, with compute advancing from 0.5 TOPS to 3 TOPS.
The deep convergence of 5G and AI has also given rise to a new category of “communication + AI” integrated chips. Qualcomm’s Snapdragon 8 Gen 4 integrates a 5G modem with an AI inference engine, and Huawei’s Balong 5000 series continues to evolve in the 5G + AI convergence direction. This trend will bring brand-new architectural challenges and market opportunities to chip design.
Overall, the collaborative development of 5G and the chip industry is shifting from infrastructure-driven to application-scenario-driven. Three directions – domestic substitution of RF front-ends, optical module speed upgrades, and edge AI convergence – will continue to unleash growth momentum. Honchak Electronics will closely monitor 5G chip supply chain dynamics and provide customers with precise selection and supply assurance.
