SMAG-KFD3
Description：
SMA RF coaxial connectors are the most widely used RF electrical connectors with small size, wide bandwidth, excellent mechanical and electrical performance. SMA series connectors have an outer conductor ID of 4.13mm, a characteristic impedance of 50Ω, and a connection mechanism of 1/4-36UNS-2 inch thread. This series of products can be customized according to customer requirements.
Application:
Widely used in microwave communications, aerospace and marine, microwave measurement equipment and other fields.
Features:
--Small size, reliable contact
--Superior mechanical properties
--Convenient docking.

FAQ:
How do you assist clients with signal transition issues between RF connectors and PCBs?
- We offer more than just connectors; we provide simulation support. Our RF engineers use HFSS to help optimize the transition layout from the connector to the PCB microstrip, ensuring minimal signal reflection for your specific board material and stack-up.
Do you provide hermetic RF connectors with Pressure Windows?
- Yes. This design is developed for waveguide or coaxial systems requiring high/low-pressure differential isolation. We use high-strength sealing glass as the pressure window, maintaining high microwave signal transparency while withstanding significant pressure differences.
Can Yolanda custom-develop connectors for specialized impedance needs?
- Yes. While 50Ω is standard, we can customize impedance hermetic connectors for broadcasting or specific test systems. Our R&D team will perform new electromagnetic designs to ensure performance metrics across the entire frequency range.
