Hi
I can do the requested RF design, based on your selected LORA IC and related peripheral circuit, and trim the PI filter at the antenna to have a match at 50Z!
You should provide to me all the design information that you currently have completed, to base on them my work for you.
Testing of the RF spectrum, and matching of the antenna to the unit will be done at my fully equipped RF Lab (see portfolio pictures).
Offer includes all redesign files for your production, and the results from these test on a prototype made by me, that I will also send to you as demo, upon completion.
You project seems to be exactly same with another one posted from a freelancer from France just 2 days ago, and another one EXACTLY SAME AS YOURS & THE FRENCH ONE from a guy from UK!. Are you working with him/those? He (meaning either of them, as BOTH have EXACTLY THE SAME DESCRIPTION AS YOURS) has a problem with the resin he uses to protect his design. Is that the same case? Or you just working or even bidding on them?
Feel free to contact me for any further clarification may needed.
Thank you!
