encapsulation of electronics

Hi everybody

We're working with SX1276 and SX1261 chips.
How much does encapsulating the electronics with epoxy resin affect the antenna tuning? Is there any experience?

Regards
Hi,

Encapsulating the passive components often has the effect of detuning the matching and harmonic filtering of the radio. I have seen some customers have more success with conformal coatings rather than potting compounds (I'm afraid I don't have any references) but with either approach risk you having to modify your design.

Thanks, Tim
