Balun options for BlueNRG?

[FHern]

I'm using BlueNRG132 (QFN32) in a custom PCB project. Currently I'm using BALF-NRG-01D3 chip, but I would like to know if there are other options of Balun Chips to use with BlueNRG and 2.4 Ghz (50 Ohm matched) antenna.

On the other hand, I would like to know how you use to build your balun circuits with BlueNRG; chip or discrete components?

Thanks in advance!

Please have a look to BLAF-NRG-02J5 with matching impedance been customized for BlueNRG-134 WLCSP and BlueNRG-234 WLCSP.
