SSMPG-JHD434X2
Description：
SSMA RF coaxial connectors are the most widely used RF connectors because of their small size, wide bandwidth, excellent mechanical and electrical performance, and high reliability. The SMA series connectors are 10-36 UNF-2 threaded connectors with a connection mechanism. The SSMA connectors are miniaturized SMA connectors with a size about 70% of the SMA. This series can be customized according to customers' requirements.
Application:
Close-packed connection between RF modules.
Features:
--Compact structure, small size, space-saving installation, suitable for high-density installation
--Connection operation is convenient and simple
--One end of the plug-end adapter has a higher insertion force than the other end, so that when the module is separated, the adapter can remain on the end with higher insertion force.

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.
