LAUNCHXL-CC1350:About Balun Designs

Part Number: LAUNCHXL-CC1350
Other Parts Discussed in Thread: CC1310, CC1350

Hi,

We use the CC1350 chip in our designs and only use the 868 MHz trace. We run into the low power issue in the design. Saying this could be due to the switch being removed, TI suggested that we use the CC1310 reference design that only works in the 868 MHz band.

At this stage, I have a question: While designing the balun circuits, is the antenna to be used on the PCB a factor in the design of the balun? Because we are not using the antenna of the reference design and I am not sure if using a different antenna will cause the balu to not work properly. Isn't using a pi-matching mesh enough to tune the antenna to the balun?

Thanks in advance for your answers.
