1. The two antenna ground pins (GANT1 and GANT2) on the 68-QFN package should be connected to the epad ground on the PCB with as short a connection as possible. Please refer to page 38 in the PSoC63 BLE family datasheet for more information. Also, please refer to the PSoC 6 MCU Hardware Design Considerations and Antenna Design and RF Layout Guidelines datasheets.
2. The matching network values will need to be tuned on the target board, also, it is better to use one more component (a pi or T) to provide for better ability to tune.
3. Could you please refer to the section '8.4 Load Capacitance Value for Designs with PSoC 6 BLE Device' in the AN95089 datasheet. Please make sure of the external load capacitance values.
Thank you very much for your support. I have read the documents you provided. The biggest difficulty is network matching;
You can refer to our PSoC6BLE development boards schematic files as reference. Make sure that the values themselves will vary from board to board and antenna to antenna.
