Re: Selectivity improvement solutions proposal for UmTRX

5. 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?
