The competitive landscape of semiconductor companies is rarely defined by technology alone; it is equally shaped by strategic choices and directional bets.

In the military analog chip sector—a high-barrier arena long dominated by foreign giants and desperate for domestic alternatives—the core question for entrants isn't merely "whether to participate," but "how to participate." Is it better to follow established pathways or forge a new direction?

From its inception, Jiangsu X-Chip Semiconductor Technology Co., Ltd. (301707.SZ) chose a path almost no one else had dared to take: forward-custom design. While competitors were busy replicating existing solutions, it began defining new ones from scratch.

This approach didn't just achieve import substitution; it drove innovation in critical equipment by introducing novel product designs. Within a few years, the company swiftly penetrated the market, built a diverse customer base, and secured ongoing R&D investment and a stable supply chain.

Since 2018, Jiangsu X-Chip has grown revenue and profit rapidly through purely organic development, validating its success across R&D, production, and sales, and cementing its status as a pivotal name in China's military analog chip space. Yet, the full story of Jiangsu X-Chip extends far beyond this achievement.

The High Barrier: Why Military-Grade Analog Chips Are So Challenging

Founded in 2018, Jiangsu X-Chip has focused from day one on military electronics support, specializing in high-reliability integrated circuits and micro-modules, with core operations in the R&D, design, testing, and sale of high-reliability analog chips and micro-modules.

Military analog chips represent the segment of the semiconductor industry with the highest technical barriers, the longest certification cycles, and the most urgent localization demands. Unlike consumer analog chips that prioritize cost-effectiveness, military-grade chips must meet five strict requirements: high reliability, long lifespan, resistance to extreme environments, high integration, and 100% independent controllability.

Global giants like TI, ADI, and Infineon have long monopolized the high-end market, while domestic firms have largely focused on low-end substitution and reverse engineering. Few companies possess forward-design capabilities, full-chain technical expertise, and military-grade product strength.

This industry has traditionally relied on "in-place substitution"—replicating foreign mature chips locally. That route offered lower risk, shorter timelines, and easier customer acceptance. But Jiangsu X-Chip, founded in 2018, veered from the start onto a nearly untrodden side road: forward-custom design.

The difficulty of military chips lies primarily in reliability. A power management chip in a missile must function flawlessly across temperatures from -55°C to 125°C, withstand intense electromagnetic interference, and perform with zero failure under severe vibration. These chips aren't just "good enough"—they must be fail-proof. Such exacting demands create an immense technical moat, leaving few competitors inside the walls; even fewer possess the end-to-end autonomy from chip design to packaging design and testing.

Currently, the company's product line spans DC/DC converter chips, linear regulators (LDOs), load and current-limit switches, drain modulation chips, and other power management categories, widely applied across missile-borne, airborne, shipborne, and ground-based weapon platforms.

In 2025, the company achieved operating revenue of RMB 640 million, up 54% year-over-year, and net profit attributable to shareholders of RMB 230 million, up 139%. In Q1 2026, revenue reached RMB 130 million, up 13% YoY, with attributable net profit at RMB 50 million, up 72%, sustaining strong growth momentum.

Micro-Modules: A Revolution in Miniaturization

Deeply rooted in high-reliability military power management chips, the company has innovatively developed and mass-produced micro-module products using advanced packaging technology, making it one of the few domestic manufacturers to supply these products in volume.

Traditional military power modules measure approximately 116mm×60mm—roughly the size of a credit card. What about Jiangsu X-Chip's micro-modules? Its highly integrated DC-DC/LDO micro-modules are less than 5mm×5mm, under a quarter of the traditional size. This is far more than a simple reduction in dimensions.

In platforms like missiles, drones, and satellites where space and weight are critical, every millimeter saved translates into enhanced performance, increased payload, and extended operational range. Using fan-out packaging technology with micron-level redistribution layers and molded vias, the company stacks control chips and passive components in three-dimensional space to create products others cannot replicate.

In 2025, micro-module revenue hit RMB 220 million, up 83% YoY, raising its share of total revenue to 34.5%, a 5.5-percentage-point increase from 2024. More importantly, only a few domestic military firms, including Jiangsu X-Chip, possess advanced packaging design capabilities for micro-modules, leaving the company virtually unrivaled in this niche.

Forward-Custom Design: From Copying to Defining

The military chip industry has long operated under the "in-place substitution" model—essentially, whatever chips exist abroad, domestic firms replicate with similar functionality to achieve import replacement. This logic supported the growth of countless military electronics enterprises over the past decade and helped China's military supply chain evolve from nothing. But the company chose a harder route: forward-custom design.

What does that mean? While others say, "I make what foreign firms make," Jiangsu X-Chip says, "I define what customers need." Take the XC6106 drain modulation chip as an example. Traditional solutions required multiple chips and peripheral components to perform certain functions; Jiangsu X-Chip integrated it all into a single 3mm×3mm chip, adding negative-voltage protection and controlling rise/fall times to within 50 nanoseconds. It occupies less than 20% of the board area of conventional solutions yet redefines the power solution for radar T/R modules. This isn't substitution—it's transcendence.

By the end of 2025, the company held 51 authorized invention patents and 56 integrated circuit layout design rights, formed 15 core technologies, and built a product matrix of over 700 models. It has been recognized as the Nanjing High-End Power Management Chip Engineering Technology Research Center. From "having substitute products" to "having superior products," the military electronics components industry is undergoing an upgrade—and Jiangsu X-Chip stands at the forefront.

Asset-Light Model with Heavyweight Quality

The company's business model is distinctive. It is neither a traditional IDM (owning fabs and manufacturing) nor a pure Fabless (design-only, outsourcing everything downstream). Instead, it follows a hybrid path: "chip design + advanced packaging design + chip testing and screening." Wafer fabrication and packaging production are outsourced, but packaging design and the vast majority of back-end testing and screening are handled in-house.

Military customers demand a level of quality that ordinary commercial clients cannot match. From wafer to finished product, a chip must pass numerous tests, screenings, and aging experiments; any oversight could scrap an entire batch. By keeping the most critical steps under its own control, Jiangsu X-Chip ensures quality assurance while maintaining the agility of an asset-light model.

This approach also fosters strong customer loyalty. The company's products have gained recognition from major military groups including China Electronics Technology Group, Aviation Industry Corporation of China, China Aerospace Science and Industry Corporation, and China North Industries Group, having supplied over 1,600 customers cumulatively. In Beijing, Nanjing, Xi'an, Chengdu, and other cities, it has deployed FAE (Field Application Engineer) teams with over 60% holding master's degrees or higher, enabling rapid response and deep technical support. In the military industry, once a customer selects a supplier, switching costs are extremely high. Jiangsu X-Chip secures its customers through both technology and service.

According to Frost & Sullivan data, China's military power management chip market is estimated at RMB 8-12 billion in 2025. Based on the company's 2025 power management chip revenue, its market share is under 5%. That figure may seem modest, but the domestic military power management chip market is highly fragmented. In the first tier, alongside Jiangsu X-Chip, are state-backed players like CETC 24th Research Institute and Sevenstar Huachuang. Among private military supporting enterprises, Jiangsu X-Chip already ranks among the leaders.

What deserves more attention is the trend. The military electronics sector is shifting from "having is enough" to "being excellent is essential," meaning the market will consolidate toward technologically capable, R&D-focused leaders. From 2023 to 2025, the company's R&D expense ratios were 14%, 22%, and 17%, respectively, with 176 R&D personnel comprising 38.18% of the workforce and over 45% holding master's degrees or higher. The accelerating pace of R&D investment is translating into a deeper product matrix and higher technical barriers.

For this IPO, the company plans to publicly issue up to 41.12 million shares, with proceeds allocated to four areas: high-reliability power management and signal chain chip R&D and industrialization (RMB 450 million), headquarters and R&D center construction (RMB 224 million), testing center construction (RMB 177 million), and supplementary working capital (RMB 120 million). Clearly, the funds are directed at the core business—R&D, capacity, and testing—with no flashy diversification.

The "signal chain chip" direction is particularly notable. The company's current core products are power management chips; signal chains represent another major analog chip category. If signal chains expand successfully, Jiangsu X-Chip's product matrix will go from "one leg" to "two legs," unlocking a broader market opportunity.

Strategic Choices Position Jiangsu X-Chip for the Long Term

The story of Jiangsu X-Chip is fundamentally about choices. While the industry gravitated toward the comfort zone of "in-place substitution," it chose the harder path of forward-custom design. While others chased short-term orders, it invested heavily in micro-modules—products requiring long-term technical accumulation. And when it could have remained a "light-design" operation, it insisted on keeping packaging design and testing screening in-house.

These choices have propelled Jiangsu X-Chip to the forefront of the military analog chip field just seven years after its founding. Meanwhile, three industry-level drivers—steady growth in defense spending, import substitution entering a new phase, and the push toward intelligent, informationized weapon systems—are opening an even larger stage for the company.
