Not that I know.

Both are different - RF processing, modulator, filters, so have to be different.

But phones can support both TDD/FDD.

Why not RRU?

I think should be possible.

If both tech working in same radio ranges you can associate diffrenet branches to diffeent sector equipment as Radio have multiple RF filter.

But radio spec should be checked at first.

Baseband in system module can support.

But RRU not seen as of now capable for it.

Is there any such commercial radio?
Same unit used for TDD/FDD.

Agree, it’s possible.

not possible, as i think RF amplifiers for TDD & FDD not same

If not same, can use different PA for TDD & FDD bands.
