In the field of high-end RF applications, the performance of connectors directly affects the signal integrity, anti-interference capability, and reliability of the system. Among them, Amphenol SV Microwave, as an industry-leading high-performance RF connector brand, is often used in high-end scenarios such as military, aerospace, 5G, and high-speed communication due to its excellent frequency response and reliability standards. However, the high cost of such products has also become an important driving factor for the increasing demand for domestic substitutes. Then, can domestic connectors find the best balance between performance and price? This article will discuss this issue by combining the product characteristics of Amphenol SV Microwave.
Amphenol SV Microwave connector: High-performance representativeAmphenol SV Microwave focuses on high-frequency, microwave, and millimeter wave connectors and components, with main advantages including:
Frequency support up to 110 GHz, meeting the requirements of millimeter-wave radar, phased array systems, and other applications
● Ultra-low VSWR (Voltage Standing Wave Ratio), maintaining high signal consistency and low reflection
●Precision structural processes, such as push-in, snap-on, and blind plug connections, facilitate high-density layouts
●High environmental adaptability, meeting the requirements of military and aviation-grade vibration resistance and corrosion resistance
These characteristics determine its irreplaceable position in various high-end products, but at the same time, its procurement cost and delivery cycle have become realistic problems for system integrators.
The current situation of domestic connectors: obvious price advantage, but performance needs to focus on core indicatorsIn recent years, domestic RF connector manufacturers have made significant progress in manufacturing technology, material proportioning, and structural design. Taking some domestic SMA, SMPM, 2.92mm and other interface models as examples:
●Price is about 30%-60% lower than imported, offering a significant cost advantage
●Frequency limit of high-frequency products has been broken through to over 40GHz-67GHz
●Insertion loss control and VSWR performance gradually narrow the gap with international products
●Some batches of products have passed reliability tests such as vibration and temperature variation in small-scale use
However, domestic brands still need to steadily advance in consistency control, long-term reliability, and batch verification. Especially in micro-structure designs such as blind-mate connections, rotating locks, and anti-EMI packaging, there is still a gap compared to Amphenol SV Microwave products.
How to find the balance between price and performance?From the perspective of project practice, achieving domestic substitution is not a "one-size-fits-all" approach, but should follow the following strategies:
Application scenario classification
● Low-frequency, non-critical applications: Give priority to the import of domestic connectors to save costs
● Intermediate frequency or sub-critical interface: Introduce domestic samples and conduct multi-round verification
● High-frequency or core signal path: It is recommended to continue using mature brands such as Amphenol SV Microwave, or to jointly customize and develop with domestic brands.
2. Grasp key parameters
Domestic connectors must meet the following parameters to achieve the "controllability" of replacement:
●Insertion loss ≤ 0.2 dB (within the target frequency band)
●VSWR ≤ 1.25
●Center guide needle fatigue resistance ≥500 insertion and extraction cycles
● Shielding effectiveness ≥80 dB (EMI protection)
Establish a test and verification closed-loop
By introducing third-party laboratories, collaborative testing on the application end, batch tracking and feedback, etc., gradually establish a product performance database, laying a foundation for domestic products in the mid-to-high-end market.
Under the increasingly evident trend of localization of connectors, "acquiring controllable performance at a reasonable price" will become the key to the success of future alternative solutions. As a representative of international high-end connectors, Amphenol SV Microwave can provide important references for domestic brands in terms of technology and application. Through hierarchical introduction, rigorous verification, and continuous optimization, domestically produced connectors are expected to achieve breakthroughs in more applications and win market trust.
