The Kirkby Microwave 85054 18 GHz Type-N coaxial calibration and verification kit.

18 Type N calibration and verification kit

The Kirkby Microwave 85054 is a coaxial calibration and verification kit for vector network analyzers. It can be used up to 18 GHz, but due to the high cost of very high quality 18 GHz loads, we can supply this with lower-cost 6 GHz loads, The kit is offered in 4 configurations, which in order of increasing cost are:

  1. 6 GHz loads. The kit will only work correctly to 6 GHz, but you can upgrade it at a later date to 18 GHz by replacing the loads. The opens and shorts are suitable for 18 GHz, but not the loads. The accuracy of the loads, even at 6 GHz, is a little poorer than using expensive metrology grade 18 GHz loads.
  2. Used 18 GHz metrology grade loads. Loads suitable for VNA calibration kits are very expensive. We sometimes sell kits with used 18 GHz loads, which have been tested using our 85054B calibration kit. Please contact us, to ask about availability, as sourcing suitable loads is not easy, so we do not always have these.
  3. New 18 GHz metrology grade loads. These are very expensive, will be supplied to special order only, and are non-returnable. Please ask for a quotation on these. The lead time can be pretty long too - about 5 weeks.

Please contact us if you wish to purchase the kit with 18 GHz loads. Due to the very high cost of these new, we can sometimes supply the kit with used 18 GHz loads. We will give you a quotation if we can supply used loads, but otherwise the cost will be much higher if new loads are purchased.
