<p>A multi-modular terminal device enables simultaneous communications over multiple wireless networks. The terminal device includes a cellular module and a Mobile TV module. The cellular module includes a dual-band transceiver, a first duplexer for duplexing receive and transmit signals in a first band, a filter for filtering receive signals in a second band, a dual-band power amplifier for amplifying transmit signals in the first band and the second band, and at least one first antenna for communicating signals in the first band and the second band of the first module. The Mobile TV module includes a Mobile TV receiver for receiving receive signals in a Mobile TV band and a second antenna for communicating signals in the Mobile TV band. The first duplexer reduces inter-module interference in the Mobile TV band caused by at least the transmit signals of the first band.</p> |
