The device side connector is known as an IPX or U.FL connector. IPEX is a brand name for a type of micro coaxial connector, which is also compatible with our product. The standard size of the U.FL connector is approximately 2.5mm in height and 3mm in width. These connectors are designed to work with a micro coaxial cable that has an outer conductor diameter of approximately 1.13mm. Please note that the size "1.13mm" refers to the diameter of the outer conductor of the micro coaxial cable. If your cable uses a smaller connector, then an MHF connector may be required instead.
