Terminal Antennas Matching

I’am designing a PCB with cellular IoT IC that will be equipped with the following antennas:

  • YE0001BA for LTE
  • YEGT001AA for GNSS
    both antennas will be outside the box and connected to the PCB via a short u-FL to SMA cable (so on the PCB there are two u.FL connector).

Traces from IC to u.FL will be 50 Ohm impedance controlled with a lenght of less than 1 cm

I am not sure to add or not a PI matching network on it basically because I do not have a VNA.
Do you suggest to add PI network anyway (with NM-0R-NM)?


Hi Sir,
We suggest add the place of Pi.
