Series D4 RF Coaxial Connector is a high-performance, compact RF connecting component featuring a push-in structure, designed to realize stable, low-loss signal transmission in high-density, mixed high-low frequency application scenarios. Compliant with relevant industry standards, it is widely recognized for its excellent electrical and mechanical stability, serving as a core interconnection part in communication equipment, industrial automation, test instruments and related RF systems.
The series boasts distinct structural and performance advantages tailored for practical application needs. It adopts a compact design, ideal for dense arrangement of multiple connectors, especially suitable for PCB backplane connections in communication devices with mixed high and low frequencies. With a fixed characteristic impedance of 50Ω, it supports a working frequency range of DC to 2GHz (up to 4GHz for enhanced models), ensuring signal integrity. Key electrical parameters are outstanding: insertion loss is as low as 0.15dB at low frequencies, VSWR is controlled within ≤1.5:1, contact resistance is no more than 10mΩ, and insulation resistance is ≥1000MΩ, effectively reducing signal attenuation and distortion.
Manufactured with high-quality materials and precision processes, the series uses brass or beryllium copper contacts with gold plating (up to 0.76μm thickness), enhancing conductivity and corrosion resistance, while ensuring stable connection even after 500+ plugging cycles. The rugged metal housing integrates a coaxial shield, providing excellent anti-EMI performance, and the push-in structure enables quick and firm installation. It can withstand extreme environmental conditions, with a working temperature range of -55℃ to +155℃, resisting vibration, thermal shock and humidity.
Its application scenarios mainly cover communication equipment PCB backplanes, industrial automation control systems, test instruments, CNC cabinets and radar modules. As a cost-effective and reliable interconnection solution, it also serves as a mainstream alternative to imported connectors in related fields, supporting the stable operation of various RF systems.
