** Anritsu K Connector®.
(1) Precision slotless contacts with the tightest tolerences to achieve best performance.
(2) Slotted female center conductors (except 7mm) with tight tolerances and very good performance.
(3) Lower cost connectors with moderate performance.
(4) Theoretically doesn't mode until 18 GHz, but the Anrtisu 85036B 75ohm N Calibration Kit is specified to 3 GHz.
(5) Fully mateable with the Anritsu V Connector®.
(6) Components for these styles have been developed by Hewlett-Packard (Anritsu) for internal test purposes, but are not readily available.
(7) Spec may still call out 34 N/cm, but we found we needed 45 N/cm for adequate repeatability.
(8) Many have maximum frequency of 18 GHz, but some manufacturers specify performance of some of their SMA product line up to 27 GHz.
(9) Considered the Production Grade version of the 3.5mm, just as the 3.5mm provides the Instrument and Metrology Grades for the SMA.
(10) IEC 169-17 describes TNCs with 11 GHz or 16 GHz maximum frequency, but expectation for many connectors is only up to 3 GHz. IEC 169-26 specifies a TNC with 18 GHz maximum frequency.
(11) EIA-550 Standard specifies 1.5 GHz maximum frequency, but the Anritsu 85039A F Calibration Kit is specified to 3 GHz.
(12) Used for precision measurements. CECC 22190 specifies torque at 25-30 N/m (approx. 20 ft/lb) in the field.
