SERIES QN, COAXIAL CONNECTORS

DESCRIPTION

HUBER+SUHNER QN coaxial connectors are avail­able with 50 8 impedance. The frequency range ex­tends to 11 GHz, depending on the connector and cable type, however most of the QN connectors are Re­turn Loss optimised for frequencies up to 6 GH z. The i n­terface is based on the inner dimensions of the N con­nector, but, instead of a threaded coupling mechanism, a new snap-lock mechanism is used. The QN interface has a very similar performance to the N, but in addition it offers an easier, faster and saver couplingoperation, helpingthe customers to savesignif­icantly time during production of their systems. The packaging density of QN increased compared to N thanks to the fact that no torque spanner is required to fasten the coupling nut. Additionally the outer dimen­sions of QN are smaller than N, leading to the advan­tage that TNC-size flanges can be used at QN connec­tors.

QN-CALIBRATION WITH ADAPTOR SWAPPING METHOD
For return Loss/VSWR measurement of QN connectors, HUBER+SUHNER recommends the following calibration method:
1. Calibration with PC7 to PC7 calibration adaptors (PC7calibration)
Adaptors: 32_PC7-U50-0-1/1--_NE (Item no. 23032719) and
33_PC7-U50-0-1/1--_NE (Item no. 23032721)
Calibration Kit
for PC7
to NWA calibration adaptor calibration adaptor to NWA
Alternative calibration with N to PC7 calibration adaptors (N calibration)
Adaptors: 32_N-PC7-50-6/1--_NE (Item no. 23032917) see page 373 or
33_PC7-N-50-6/1--_NE (Item no. 23032916) see page 374
Calibration Kit

to NWA calibration adaptor calibration adaptor to NWA
2. Exchanging of the calibration adaptors with the required QN adaptors
32_PC7-QN-50-1/1--_NE (Item no. 23032720) see page 377 or 33_PC7-QN-50-1/1--_NE (Item no. 23032722) see page 377
DUT
Thanks to the same electrical length and the same return loss behaviour of all these adaptors, the adaptor swapping method can be used (same dimensions of all electrical relevant piece parts in these adaptors).
