Question

Hello,

We are currently using a10192 in our development.

We have implemented the basic design guidelines provided in the A10192 datasheet, and the PCB is a 2-layer board. However, we are observing that the resonance is forming around the 2.55 to 2.6 GHz range. Despite trying various matching combinations, the impedance is not shifting into the 2.4 GHz band as intended.

Could you please confirm if the A10192 component has been manufactured according to the specifications provided in the datasheet?

Additionally, we would greatly appreciate any guidance or recommendations for improving the situation described above.

Thank you very much.

Best regards,

Hi,

Have you tried starting using the 0 ohm link to check the natural resonance of the antenna?

Using the full pi matching network is also possible even though the datasheet suggested 2 components.

Let me know if you have tried those methods
