We have a small 1x1 inch board which has the ESP32-PICO-D4 on it with a ceramic chip antenna. Looking for a very good RF engineer to pick the matching values for perfect TX RX range of the 2.4ghz transceiver. The board is already done and we have samples. You can make a sample on your side or we can ship a populated board to you. Please DO NOT APPLY if you don't have EXTENSIVE RF experience and all the needed equipment.

Hello, I am an electronics and telecommunication engineer and my major is wireless systems design. So far I have designed many antennas and their related parts such as matching circuits, filters(lumped/distributed), phase shifters, power dividers, etc.. So I am sure that I can help you with your matching circuit(if this is the only problem). So just let me know. Best regards

Hi!! We're a team who works with RF communication. We developed an RF module that can read/received digital input signal, analog input signal such as temp, pressure, humidity and transmited digital/analog output signal via RF using LORA protocol with small power consumption. We could help with your device, please tell us more about you requirements and specification. I can share with you all the documentation and videos about the equipment with developed if you want.

Matching is done using a VNA on the actual board. Nobody can predict the matching components theoritically. I am in the RF design stuff(look at my portfolio) and own VNA. I can do the matching exercise for you. I would have fabricated the board myself but currently due to tension between India and China we are getting difficulty in getting packages from china. I need boards to be shipped by you from any country other than China.

10 years+ of microwave experience. Have spectrum analyzer, network analyzer, played many antennas including ceramic antennas. Matching is a must-do job every day. But my quotation is high, because making good products is a lot of work. Interested to contact me.
