Antenna type of QM33120WDK1 development kit

Ultra-Wideband
1

Hi there. I am trying to develop on QM33120WDK1 development kit, and I saw in the code that there are 3 types of antenna:

  • MONALISA CHANNEL 5/9
  • JOLIE CHANNEL 5/9
  • CUSTOM

I am reffering to …\Src\UWB\dw3000_pdoa.c

Please help me understand the antenna types, their difference, and which should I use in my QM33120WDK1 development kit ?

Another question - there is a nice calculation in “fpdoa2aoa” function, that is not present in some other code example from qorvo - I mean to “ex_01h_simple_tx_pdoa” and “ex_01h_simple_rx_pdoa” - which only has rad-deg convertion (plus some extra consstants of 1<<11 etc.)

thanks, Yair

Hi yair,

QM33120WDK1 comes with the Jolie antenna included. So it can support both channels and give you an idea about your future application.

The Mona Lisa antenna is the previous generation antenna for our old development kits. Therefore, you can neglect that part in the code.

If you want to design your own antenna or use another antenna, you need to characterize the performance of that antenna and the CUSTOM field allows you to use the characterization data.

Kind regards,
Emre
