Re: RF Demo Kit Testing tutorial released

The RF Demo Kit NWDZ Rev-01-10 is available via Ebay for about 15 EUR.
A documentation can be found at: . I will just extend it a bit about details and *practical* *usage*. For more *details* see the *wiki* *page*: /g/nanovna-users/wiki/RF-Demo-Kit-use The micro coax plug is named U.FL/IPX, 50 Ohm, about 2mm diameter. For more details see on . /!\ Excerpt: "Female U.FL connectors are not designed with reconnection in mind, and they are only rated for a few reconnects (approximately 30 mating cycles [5]) before replacement is needed. The female U.FL connectors are generally not sold separately, but rather as part of a pigtail with a high-quality 1.32 mm doubly shielded cable, which allows for a low-loss connection." /!\ The cable crimp in the little U.FL connector in not very solid. In order to avoid a cable and plug separation you should solder the coax cable shield crimp, see the picture on the right. I made once this experience, and it was very difficult to repair the cable connection. In order to fit the center wire, you need to solder it with very little tin, and open the socket a little with a needle. And you need some patience, good light and a good magnifier glass. /!\ To make a connection with the U.FL coax plug, just use your finger, no tool. Use a little flat screw driver to lift off the U.FL female plug. 73, Rudi DL5FA |
