#567 NANOVNA Demo Board with SMA Connectors

Episode 567
I've created a board that uses SMA connectors. I will post the Gerbers when complete.

Glad you're working on this, my bonehead solution thought was to simply extend the connections with U.FL to panel SMA jumpers in a box but boy that was gonna get really expensive and totally overkill for this project. Your solution much more elegant!

[glaura]

i think it's really helpful for me and i will recommend this video to my friends.and have you ever used SMA connectors in elelcbee from China? thanks!

[EWDDR]

Friend! And where can you get the circuit to solder the rest of the details?

[JohnTarbox]

In a previous video you discussed the quality differences between the USA and Chinese-made connectors. What SMA connectors are you ordering for this project and from what source?

[hectorgonzalez]

Great job !!!, btw what is the board thickness(1.57, 1.69)??

[robertralston]

Much rather have the SMA instead of the U.FL connectors. Is there a list available of the parts, like for the filters?

Hi, I ordered your board from PCBWay. I wondered what is the microstrip with coplaner lines size and spacing. My software calculation says that the line width should be 3mm and the spacing on the surface should be 1.9mm on a 1.6mm thick board with one once copper. I see on your board the width is about 2mm and spacing is 1mm. Did you measure your line impedance?

Does JLC PCB have a files repository with your Gerber so folks could replicate your project? I know a bunch of folks here in our club would be interested. TNX!

Do you have a Github account? you can post the files there. Also, people can help with different designs. Thanks, MikeK
