Andrey,
What I proposed is to use a side connector to connect UmTRX PCB and RF board OCB side-to-side, without a cable. This way we need two connectors and no cables at all. Downside of this solution is less flexibility in the RF board placement, but do we really need this flexibility?

Hi Alexander.
Actualy I don't know side-type connectors for cable. I suggested you PCB side connector (like PCI) for debugging only. Moreover, there are a lot SMD connectors for IDC flat cable, BHS-10 for example.
Best regards, Andrey Sviyazov.

- Regarding connectors, I only can suggest to use the two angle
SMA-female connectors for outputs which will stick out through the panel of the housing (as you can use the angle SMA connectors, but for GPS and CLK_I/O on the UmTRX board). At the same time for the internal 4 connectors we can use some cheap like U.FL and cable assemblies U.FL-MCX or U.FL-U.FL. Signal CLK_26MHz, 6.5VDC, SPI and Switch controls will go via IDC control connector.
IDC connectors on a UmTRX and on a RF board will be connected with a flat ribbon cable?
Why don't you want to use a side connector?
