Other Parts Discussed in Thread: CC1310
Hello All,
I have designed a custom PCB based on the reference design for the CC1310 LaunchPad.
www.ti.com/.../LAUNCHXL-CC1310
The uC is programming, and running code, when I attempt to send data through the radio, the software reports a successful transmit, but I am not able to get any data received from my LaunchPad, which
I have programmed as the receiver.
I'm really not an RF expert, but I positioned the RF front end components as similarly as possible to those on the reference design, and requested that the board stackup be the same as that from the reference design.
After re-reviewing the BOM, I realise that for C21 in the reference schematic, the capaitor that connects RX_TX to ground, I requested a 0.1uF instead of a 100pF capacitor, I guess that will have a pretty severe impact.
I also realise that when providing my manufacturer with a BOM, I only specified the part type and value, e.g. Inductor 7.5nH, but I now see that in the TI BOM, there is much more detail, specifying RF inductor, non-magnetic core.
Please can someone tell me which components in the RF front end are likely to be the culprit of my non-functional radio? I don't mind re-soldering the whole front end if needs be, but I'd like to only change the parts that I need.
Which are the most likely causes of my problem? What can I do to get it working? and how much can I test this, all I have is a scope.
Thanks in advance.
