The 908-22101-TC: It is rated to 6 GHz maximum frequency, making it suitable for wireless modules, GPS antennas, and test equipment where board space is tight.
Surface-Mount Termination and Board Fit
This MMCX jack terminates via surface-mount solder pads — the shield and center contact both solder to the board. The dielectric is Liquid Crystal Polymer (LCP), which holds up to reflow temperatures without wicking or deformation. For a board layout engineer, the footprint needs to match the MMCX standard pad pattern; the 50 Ohm impedance is maintained by keeping the signal trace width and ground clearance consistent with the connector launch.
