Part Number: CC2540

Hi team,

my customer is looking for a small antenna for the CC2650 and found the CC2540EMK-USB EVM. Can you provide me the design data of the PCB? What kind of antenna is used there? Do you have other recommendations for a small PCB antenna?

Thank you and kind regards,

Felix

Hi Felix,

Please refer to this app note for more information about the AN043 PCB antenna: www.ti.com/.../swra117d.pdf This is the smallest 2.4 GHz PCB antenna we have a reference design for. If your customer require even smaller footprint a chip antenna can be used: www.ti.com/.../swra092b.pdf

Best regards,
Simon
