Quick-locking N-type boosts bandwidth,
cuts costs
In addition to having all the advantages of a quick-lock interface, the CQN achieves electronic performance equivalent to the original Type N connector from DC to 11GHz.
In 2004, the Quick Lock Formula (QLF) Alliance of Huber+Suhner, Radiall, Rosenberger and Amphenol released the QN, a quick-locking replacement for the widely applied Type N connector As a result of the new snap on interface, this design offered numerous advantages over the threaded connection of the N type: advantages that include 10x faster mating and demating, significant conservation of space because torque wrench clearance was no longer required for installation, and the ability to rotate the cable 360 degrees after attaching the connector

Punch down and earth strap for connector
The RJ-LnxxT IP67 rated, sealed, industrial RJ-45 connectors, available in the UK from Aerco, are now available with IDC punch down and earth strap terminations.
However, in spite of these distinct benefits, the sphere of application for the QN has been limited almost entirely to low-frequency basestation systems because of this connector's inability to meet the high performance standards set by the original Type N.
The QN's principal flaws are that it fails to maintain the basic structural parameters of the N type and its complex design has resulted in a very high manufacturing cost.
These deficiencies have led Anoison Electronics to develop its own quick-locking N-type connector, the CQN, which the company reckons successfully resolves all these issues.

Whereas the electronic performance of QN is only really optimised up to 6GHz, a cleverly designed locking mechanism has allowed the CQN design to preserve the structural dimensions of the traditional Type N: in which the inner conductor is 3.04mm and the internal diameter of the outer conductor is 7.00mm.
The result is that in addition to having all the advantages of a quick-lock interface, the CQN achieves electronic performance equivalent to the original Type N connector from DC to 11GHz.
With these new performance capabilities, the range of application for the quick-lock N can be extended significantly.
And whereas the QN has a very high manufacturing cost because it requires a large number of component parts that are difficult to process, the CQN design is elegant in its simplicity.
It is quick and easy to produce and on average requires 50% fewer materials to manufacture than the type N and 20% fewer than the QN.
The CQN has 50ohm continuous impedance with no reflection, an engagement/disengagement force both of 30N and a durability of 200 cycles.
Although the standard interface retention force of CQN is 200N, the ring-like locking sheet that comprises the locking mechanism can be thickened to allow it to reach as high as 450N.
Anoison Electronics is also manufacturing improved designs of the quick lock SMA connector QMA, called CQMA and Mini-CQMA.
