4.3-10 RF adapters are an IEC 61169-54 standardised coaxial RF interconnect designed for 4G-5G cellular applications up to 6 GHz. They are used to interconnect a component with a 4.3-10 connector to RF equipment having different connector types.
The 4.3-10 connector can be identified by its medium size and unique two-part design. It consists of an outer 10 mm threaded shell and a 4.3 mm inner contact pin or socket, depending on the gender. The male connector has an inner pin, while the female connector has an inner socket.
4.3-10 RF adapters are often found in telecommunications, particularly in mobile communication antennas and equipment. They are appreciated for their low Passive Intermodulation (PIM) performance, IP67 weatherproof design, and high power handling capability, which makes them ideal for modern cellular systems like 4G and 5G.
