Calibration service assures coax
connector specs
The 7-16 precision coaxial connector was developed during the 1960s during an era when such connectors were beginning to become standardised.
The 7-16 precision coaxial connector was developed during the 1960s during an era when such connectors were beginning to become standardised It is currently experiencing a resurgence of interest due to its particular suitability for certain applications in high performance military systems and cellular basestation installations, including high power 3G systems

Service keeps radiation monitors up to scratch
Calibration service ensures hazard monitors provide consistent and accurate readings.
The name of the connector comes from the nominal values of 16mm at the interface for the internal diameter of the outer conductor, and 7mm for the diameter of the centre conductor.
The exact ratio is chosen such that it gives a nominal impedance of 50ohm.
It is a precision connector with excellent electrical performance including low insertion and return loss, good connection repeatability and high power handling capability and can cover a frequency range from DC to 7.5GHz.
It is mechanically robust and exhibits low passive intermodulation (PIM).
High quality devices fitted with 7-16 connectors are available for use as standards for calibrating vector network analysers (VNAs), reflection analysers and other similar measuring instruments.
In response to the growing demand for assurance of measurements of devices in this connector type, NPL has set up calibration services with traceability to UK national standards (and hence the SI).
Currently impedance (ie complex S-parameters) and antenna measurements are available with attenuation and power measurement services coming soon.
A service providing measurements of characteristic impedance of precision air lines in this line size is also available.
