As a result, the equipment for such installations is becoming ever smaller; therefore, demanding highly com- pact, high performing coaxial RF connectors. The growing demand for new generation equipment within the market re- quires a high-performance solution with exceptional benefits and features. 5G is expected to be 100 times faster than 4G LTE and will provide a tenfold increase in broadband connec- tion speeds. To achieve this many more radio heads for de- ployment in small cell sites will be necessary. This is making reliable, low-cost RF connectivity more mission critical than ever for enabling numerous micro cell applications. Enhanced Protection From the lessons learned from 4.3-10, the NEX10 ® has been evolved as a small and highly robust connector, ideal for applications with limited space. With an optimized design rather than just a scaled down 4.3-10, the inherent weak points of the 4.3-10 connector family have been fully addressed during the design and de- velopment of the NEX10 ® connector series. Particular attention was focused on the following areas: • Provision of a protected slotted outer contact element which cannot get damaged • Additional protection of slotted contact elements by surrounding it with dielectric • Jack outer contact with no fragile elements to prevent potential damage if wrong connector inserted Key Features The NEX10 ® offers excellent PIM stability of -166 dBc, high flexibility of coupling mechanism (quick lock and screw), and a ruggedized compact design. With a flange height of just 12.7mm, it is the smallest coax connector system for small cell mobile communication on the market. • Small size, 12.7 mm flange height • Screw and push-pull coupling • -166 dBc PIM, independent of torque • Robust design for outdoor use • Operating up to 20 GHz with excellent return loss • Cable connectors for up to ½” corrugated cables • Blind mate for panel connection as well as test and measurement applications Application Examples The NEX10 ® interface is extremely versatile and highly suit- ed for applications requiring PIM stability in compact spac- es. For example, small cells, low-power base stations, dis- tributed multi-operator/multi-band antenna systems (DAS), Multiple Input Multiple Output (MIMO), and in-building ar- chitecture and street furniture. NEX10 ® is ideal for making quick and reliable connections in a wide range of limited space applications, from small cell anten- na and street furniture in urban environments to base station antennas with a high number of ports. In summary, mobile net- works increasingly require RF signal transmission to be imple- mented where space is highly constrained. Ensuring the low- est possible signal interference is a further challenge in terms of mitigating the additional potential for increased PIM. The NEX10 ® connector series is already proven in the challenging mobile network application areas mentioned in this application note.
