RF Bluetooth front end circuitry design of nRF51822 QFAA-G0

[Fenglong]

According to Page5 of nWP-018, if we compare QFAA G0 to C0, G0 doesn't have a valid version reference design with the right balun. But G0 and C0 have the same valid reference design with LC matching network.

So how to explain that the reference LC network design works for both G0 and C0, but the balun only works for C0 and not G0? Are there any difference in the Nordic chip's RF frontend?

thanks, Fenglong
