NMD is a reinforced mechanical structure port, with the characteristics of sturdiness and durability, which can prevent the precision coaxial port of the test cable (test adapter) from being damaged during use. NMD stands for Network Measurements Division, which can be divided into NMD connectors and NMD adapters. When designing or selecting products, RF engineers and users need to understand the characteristics of NMD connectors/adapters, and refer to the NMD interface standard, to correctly match all the same types of NMD connector/adapter ports in the industry.


NMD connectors/adapters are generally used for Vector Network Analyzer panel ports, electronic calibration parts, VNA high-precision amplitude-phase stable test cable components, etc.


NMD port types include NMD 3.5mm, NMD 2.92mm, NMD 2.4mm, NMD 1.85mm, etc. The 50-ohm NMD interface standard of Wavelength complies with the manufacturing standards of the NMD precision instruments in the RF industry. The specific NMD interface standard is as follows:
