Technological progress drives the growth of the electronics industry
The three main trends driving the growth of the electronics industry in the aerospace industry are electric propulsion, autonomous systems, and real-time analysis supporting the Internet of Things (IoT). In order to achieve the goals of efficiency, emission reduction, and controllable operating costs, connectors that can handle high-speed data, manage real-time data streams, provide advanced diagnostic functions, and stabilize power are needed. These connectors must also meet strict safety and compliance standards.

The field of national defense is moving towards digitization, and in this process, the importance of connectivity and network security is becoming increasingly prominent. To meet these requirements, defense organizations urgently need secure data transmission mechanisms, advanced autonomous systems, and strong supply chain visibility. Filter connectors can effectively resist electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring communication stability, while sturdy and durable components provide solid support for the reliability of the entire autonomous system. In addition, real-time tracking technology and diversified procurement strategies are becoming increasingly important.

Connection solution
In the field of national defense, the current complex environment urgently requires advanced connectivity solutions that can seamlessly integrate with existing infrastructure to help achieve key results. To meet this growing demand, DigiKey has further enriched its selection of Molex products. This includes our EMI/RFI shielding products, carefully crafted to protect critical aviation electronics and communication systems. It is worth mentioning that since the acquisition was completed in early December, AirBorn, Inc., a subsidiary of Molex, is about to launch a full range of aerospace and defense solutions, which is expected to bring more high-quality choices to the industry.

Fixed RF coaxial attenuator
Providing precise signal power control and excellent signal integrity, the fixed RF coaxial attenuator (Figure 1) ensures long-term stable and consistent performance with high precision and durability. In various aerospace and defense application scenarios, they often face harsh conditions, and these attenuators are the ideal choice to meet the demand for reliable accuracy in such situations. These devices offer various connector types, different fixed attenuation values, and a wide frequency range
