I have designed a circuit board with a LORA antenna 868Mhz (with pi filter and 50ohm) and an integrated trace antennas on the PCB, designed per manufacturer design recommendations with pads for a "PI" filter for impedance matching the antennas to 50ohm impedance. I'm looking for a RF engineer who can select components (capacitors and inductors) for the PI filter and test the circuit boards with the proper equipment, a network analyzer. Please only bid if you have the correct equipment and experience with this type of antenna tuning / impedance matching. Thank you.

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!

Hi dear customer. I have some questions 1. How much antennas need to do this work, 2. Please tell me antenna bandwidth. P.S. I have NI PXIe-5632 VNA

Hi, I am a PhD scholar with specialization in RF and microwaves with prime focus on antennas, filters, mixers, Low noise amplifiers, mixers, oscillators, PLLs and much more. I can easily handle your task. I have in-house LPKF PCB manufacturing machine and also Vector network analyzer in my lab which I can use to test the filter. The bidding cost includes the cost of LPKF manufacturing and the nedded RLC components. You may contact me for more details Thanks
