Abstract
A multi-modular terminal device enables simultaneous communications over multiple wireless networks. The terminal device includes a first transmit filter connected to a first transceiver corresponding to a first wireless network for filtering first transmit signals, and a second transmit filter connected to a second transceiver corresponding to a second wireless network for filtering second transmit signals. A first antenna connected to the first transmit filter sends the first transmit signals from the first transceiver and receives first receive signals. A second antenna connected to the second transmit filter sends the second transmit signals from the second transceiver and receives second receive signals. The first transmit filter attenuates interference signals from the first transmit signals in a receive band of the second receive signals, and the second transmit filter attenuates interference signals from the second transmit signals in a receive band of the first receive signals.
