Embodiments relate to a multiband transceiver apparatus (100), comprising a first transmit path (110) operable to transmit a first transmit signal ( sig 1) in a first radio frequency band (RF 1 ), wherein the first transmit path (110) comprises an input (112), an output (114) and a first feedback path (116) from the output towards the input of the first transmit path, a second transmit path (130) operable to transmit a second signal ( sig 2) in a second radio frequency band (RF 2 ), the second radio frequency band (RF 2 ) being different from the first radio frequency band (RF 1 ), wherein the second transmit path (130) comprises an input (132), an output (134) and a second feedback path (136) from the output towards the input of the second transmit path, and a cross-talk canceller (150) operable to cancel cross-talk from the second feedback path (136) to the first feedback path (116) and/or to cancel cross-talk from the first feedback path (116) to the second feedback path (136) of the multiband transceiver apparatus (100) |
