Antenna interface - missing values

[tzutu]

Hi there,

I am looking to tune my antenna. I searched in the documentation how and I found a page without values. Can you please give me some guidance?

Our product is for the European Market. We are using an external antenna

This is the incomplete page I found: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fnwp_033%2FWP%2Fnwp_033%2Fnwp_033_antenna_tuners.html

Hi, 

tuning an antenna depends on the antenna you have chosen and the RF design. 

Is this for a nRF9160 LTE antenna? 

Is it a multiband antenna? Chip antenna or a PCB antenna?

Are you using antenna tuners circuity? - The link you sent. How to use antenna tuners, as we have done in our example design with nRF9160 Thingy. 


Best regards,

I would like to use this antenna form your data sheet: https://cdn.taoglas.com/datasheets/FXUB65.07.0180C.pdf

Are you planning to use is both as LTE and GPS antenna or only one of the two?

This is an external antenna, that you can connect to the pcb.

Just LTE. Yes, I am connecting it to a PCB. 

Do I have to implement matching circuit for this antenna like the following one?

Not from what I can see in the datasheet for the antenna. 

You can ask the antenna vendor, if you want to be sure.

Best regards,
