Design me a Product

Budget €250 - €750 EUR
Bids 4
Average Bid €819
Status Closed

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.
