New applications such as small cells, MIMO and DAS are driving the development of even more compact network equipment and smaller connectors to support the further miniaturization of antennas and RRUs. The new 2.2-5 connector system is derived from 4.3-10 and delivers the same excellent electrical performance while only being half the size.

It is now well on its way to being standardized, and SPINNER has already launched the first high-precision calibration kit for it.
