I had made some UHF connector measurements recently and this discussion encouraged me to publish them. If interested see http://www.w0qe.com/Technical_Topics/uhf_connector_compensation.html 73, Larry
Very interesting and well done... Thank you! -- Thanks and 73's, For equipment, and software setups and reviews see: www.nk7z.net for MixW support see; http://groups.yahoo.com/neo/groups/mixw/info fo
Larry, I'm not a fan of UHF connectors, but your article was interesting, but there are a few things I don't understand. 1) You don't describe how you calibrated the VNA which is not so easy with PL2
That page is a keeper, thanks. Ive also heard many in the weak signal UHF community say that the VSWR reaches a peak at around 432 and then slowly decreases to where it is again useable at 903 and 12
Dave, I am also not aware of any UHF calibration standards. I used the HP cal kit which is an offset (both open and short) cal kit with the open also having a fringing capacitance. The VNA removes th
I don't think there ever will be, as the connector has an undefined impedance, so its hard to see how one could make any sort of standard. The short does have some inductance too, though you can't en
Larry has done some very nice work here, which I've used by adding cable to those connectors -- one pair to connect the cable to the source, and a second pair for connection to a load. k9yc.com/UHFCo
This reminds me of all the discussions and outright arguments we had when I worked in the 12-75 GHz region at a few companies and well above 200 GHz at BAE. At one place the 2 PhD's in R&D called in
