QCA4010 balun

We're developping a battery-powered board based on the QCA4010.

We are using the balun suggested by Qualcomm:

Maglayers DLU-2016-2G4S5-A1-QS

However, some of these baluns develop a leakage current of 3-4mA after some ageing. This problem is recognized by the manufacturer but it does not seem like it will be solved soon.

- Are there any alternative baluns known (apart from the implementation in discrete components)?

- We're also looking to power off the balun with a FET when not needed; are there signals available on a QCA4010 pin that can be used to drive such a FET?

- Are there API functions available to monitor the Wifi status, so we can easily drive an IO pin for the same purpose?

 

Thanks!

For now we have found that pins ANTA/B/C/D should be available for exactly this purpose. However, no info is found on how to configure these. Any API functions available? I can't seem to find any reference to this.
