Recently, the satellite communication sector has become hot again. SpaceX is pushing forward with the "direct phone connection" project, aiming to enable ordinary phones to access the space internet directly through the Starlink satellite network. It sounds cool, but the underlying industry chain is even more interesting—many companies are profiting from it.

What are the main segments of the supply chain? Simply put, three parts: chips, antenna RF, and satellites with rockets.

**Who is making chips?**
Qualcomm, MediaTek, and Samsung Electronics are all developing mobile chips and modems with integrated satellite communication functions. These giants are competing for dominance, as this is the future direction of mobile phones.

**Antenna and RF front-end are the real money makers**
This is the key to transformation and upgrading. Imagine, a phone needs to receive signals from distant satellites and also combat attenuation caused by high-speed movement. The requirements for antenna performance are quite high.

Shenwei Communications has been repeatedly reported as the exclusive supplier of high-frequency connectors for SpaceX's Starlink ground terminals, producing highly reliable components that can operate in extreme environments. The market is watching this company's future performance in the mobile antenna field. Tongyu Communications supplies Starlink terminals with MacroWiFi antenna modules. As you can see, both companies sell antenna-related products, but their entry points differ.

The satellite side also requires high-performance communication payloads. Tianyin Electromechanical supplies star sensors for Starlink satellites—these are critical components for attitude control and indispensable.

**Satellites and launch services are the infrastructure**
SpaceX plans to launch tens of thousands of satellites, especially the V3 model supporting direct phone connection. This requires strong independent R&D and mass production capabilities. Don't forget, they also use reusable rockets (Falcon 9, Starship) to lower launch costs.

An interesting phenomenon here is that some Chinese companies are also involved. Parker New Materials, Yingliu Shares, and Zaisheng Technology, leveraging their expertise in aerospace-grade special materials (high-temperature alloys, thermal insulation materials) and precision components (engine castings, forgings), have entered SpaceX's supply chain.

**A few investment pitfalls to avoid**
First, keep a close eye on technological breakthroughs and ecosystem development. Track SpaceX's satellite launch progress, mobile phone manufacturers' cooperation trends, and chip mass production status—all directly impact the actual benefits of the industry chain.

Second, verify supply chain partnerships carefully. SpaceX rarely discloses its suppliers publicly; much information online is from market analysis or indirect corporate disclosures. Claims of exclusive supply or sole sourcing should be questioned, and the business share should be considered.

Finally, do not ignore risks. Technological iteration, market competition, and geopolitical factors could all deal a blow to entrants. When evaluating stock price movements, these factors' impacts must be considered.
