Both NEX10 and 4.3-10 connector interfaces are low PIM connector interfaces developed for 4G/5G small cell applications. NEX10 has been jointly developed by HUBER+SUHNER, RADIALL and ROSENBERGER, where as 4.3-10 is a more generic standard offered by a number of connector manufacturers. The differences between these connector types has been summarized in the table below:

Connector TypeNEX104.3-10
Impedance50 Ohms50 Ohms
Frequency RangeDC to 20 GHzDC to 12 GHz
PIM> 166 dBc @ 2 x 43 dBm> 166 dBc @ 2 x 43 dBm
Return Loss> 36 dB from DC to 6 GHz> 36 dB from DC to 4 GHz

> 30 dB from 6 to 10 GHz> 30 dB from 4 to 6 GHz

> 20 dB from 10 to 20 GHz
Mating Cycles> 100 (regular applications)> 100 (regular applications)
> 500 (Test & Measurement Applications)
Engagement Force (Push-Pull)50 N100 N
Disengagement Force (Push-Pull)40 N80 N
Recommended torque (screw-type)3 Nm5 Nm
Degree of protectionIP-68IP-68

Note: The source of these values is Rosengerger. Though they are one of the companies that developed the NEX10 connector interface, they also develop 4.3-10 connectors. So this data should be non-bias.
