Maury Microwave was founded in 1957 and is headquartered in California, USA, serving as a global leading provider of RF/microwave testing and measurement solutions. Its core products include precision adapters, test cables, calibration standards, Gage Kit (connector measuring tools), and other high-end devices, with application coverage in aerospace, 5G communication, semiconductor, and research institutions. Maury's products are renowned for their high precision and stability, especially in millimeter wave testing and high-power microwave applications, demonstrating extremely high reliability and performance assurance.
The relationship between material quality and connector performanceIn the connector field, the choice and quality of materials directly determine the electrical performance, mechanical performance, and service life. Taking Maury's high-frequency test connector as a reference, the impact of material quality on performance can be understood from the following aspects:
Selection of conductive materials
High-performance connectors commonly use gold-plated or high-purity copper materials to ensure low contact resistance and stable signal transmission.
●If insufficient choice is made for conductor materials in domestic substitute products, it will lead to increased insertion loss and deterioration of return loss.
Insulation and support materials
●Maury products often use low dielectric constant and low loss materials (such as PTFE) on medium materials to ensure stable impedance matching at high frequencies.
Domestic connectors, if the insulation material process does not meet the standard, will show excessive dielectric loss and fast signal attenuation in actual testing.
Coating and anti-corrosion technology
High-end connectors will use wear-resistant coatings and anti-oxidation treatment to ensure that performance does not degrade after repeated insertion and removal.
Domestic connectors are gradually improving in surface treatment, but they still need to continuously optimize in terms of coating uniformity and durability.
4. Mechanical strength and dimensional accuracy
Maury's Gage Kit is used to verify the mechanical tolerances of connectors, ensuring stable mating and frequency performance.
●If domestically produced products have slight deviations in material hardness and processing accuracy, their measured performance may exhibit VSWR (Voltage Standing Wave Ratio) fluctuations at high frequencies.
Section 2: Sharing of Domestic Connector Material Quality MeasurementThrough comparative experiments with multiple domestic connectors, we found that:
●Significant performance differences in high-frequency bands (>18 GHz): material purity and coating uniformity have a significant impact on insertion loss and return loss.
● Insertion and extraction life and mechanical stability: High-quality materials maintain stable performance after hundreds of insertions and extractions, while ordinary materials show poor contact.
●Environmental adaptability: Connectors with insufficient material processing technology are more prone to performance degradation in high temperature and humidity tests.
The test shows that domestic connectors can meet most needs in medium and low frequency applications, but in high frequency precision testing scenarios, continuous optimization is still needed in material selection and process control.
The material quality of connectors is a key factor in determining their electrical performance and reliability. Maury Microwave's products have set high standards for the industry and also provided a reference direction for domestic substitution. With continuous breakthroughs in material technology in China, domestically produced connectors have a promising application prospect in fields such as optical communication, microwave testing, and data centers.
