Question

Hello,

For our project, we will be using either the M20047 or M20057. The datasheet does not explain the R1/L2 tuning components.

Questions

1. The pcb (4cm x 2cm) we will use for our project will have LTE, BLE, GPS ANT. I would like to know if M20047 or M20057 would be better.

2. if there is a sheet for R1, L2 tuning components, please share it.

Thank you.

Hi Sir,

technically, if there are multiple radio systems in the device, then M20057 is recommended.

please be sure that the M20057 has to be place at PCB long edge side.
for the document about the antenna tuning, we will send it to you later.
