Abstract: Embodiments relate to a multiband transceiver apparatus (100), comprising a first transmit path (110) operable to transmit a first transmit signal (sig1) in a first radio frequency band (RF1), 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 (sig2) in a second radio frequency band (RF2), the second radio frequency band (RF2) being different from the first radio frequency band (RF1), 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)
Abstract translation: 实施例涉及一种多频带收发器设备（100），包括可操作以在第一射频频带（RF1）中发送第一发射信号（sig1）的第一发射路径（110），其中第一发射路径（110）包括输入 （112），从所述输出到所述第一发射路径的输入的输出（114）和第一反馈路径（116）;第二发射路径（130），其可操作以在第二射频中发射第二信号（sig2） （RF2），所述第二射频频带（RF2）与所述第一射频频带（RF1）不同，其中所述第二发射路径（130）包括输入（132），输出（134）和第二反馈路径 （136）从所述输出朝向所述第二发射路径的输入，以及串扰消除器（150），其可操作以抵消从所述第二反馈路径（136）到所述第一反馈路径（116）的串扰，和/或 从第一反馈路径（116）到多频带的第二反馈路径（136）取消串扰 收发器装置（100）
