Part Number: CC1120EM-420-470-RD

We have a CC1120 design (433MHz band) on a new product using a helical antenna.

1. Can TI review our design (layout and schematic)? Do you normally do this?

2. Can TI provide any recommendations when using a helical antenna?

Hi,

Sure. We can review your schematic and layout.

For the helical antenna, try to maximize the placement clearance distance to GND to increase the efficiency. Will you be using a wire helical antenna or PCB helical ?

Regards,
Richard

Thanks. I will upload files for review. We will be using a wire helical antenna.

Hi Richard.
Can we send the pcb layout and schematic files for review via email as I'm not allowed to post company confidential designs on the forum. My work email is: sudesh@prepaidworl.co.za.
Can you send me an email and I will respond with the files?
Thanks for the support.
