I got a quote from Pasternack today. They can't do 20 GHz in SMA so suggested 3.5 mm, which would be fine. They actually quited for 2.92 mm on the other end, whereas I need 2.4 mm, but the price was the US equivalent of about $220/cable. > Citrus Cables does nice quality, inexpensive work, and they have oddball stuff like MMCX if you need it. I use them for general purpose jumpers a lot. > http://www.citruscables.com or http://www.citruscables.biz They don't seem to do the high precision stuff. They have things like BNC and reverse SMA, but I don't see 2.4 mm. > RFCoax - I use them for semi-rigid and formable type cables > http://rfcoax.com Someone else suggested them. They do what I want, and the price is much lower than Pasternack. $85-$95 depending on the length, and that includes test data. I would feel a bit happier paying $5 extra for test data. Hopefully it means that they really are tested! They also do the really high frequency 1.0 mm connectors, so it gives me some confidence that they are serious about cables. > Tensolite (part of Carlisle) > http://www.carlisleit.com/products/assemblies/rfmicrowave-assemblies > Formable semirigid > > Axon > http://www.axon-cable.com > These guys are in the UK, and they have very low loss cable. I don't know about one-off assemblies. I will ask. I am certain that this mod will degrade the dynamic range, but when it was calibrated, it exceeded the spec by about 8 dB, so a bit of loss can be tolerated. But the benefits far outweigh that.
