Abstract
Systems and methods related to time-division and frequency-division duplex protocols for wireless applications. In some embodiments, a wireless architecture can include a radio-frequency (RF) path configured to support a first modified time-division duplex (TDD) band operation and a second modified TDD band operation. Such a wireless architecture can allow consolidation of signal paths and/or re-use of components such as filters and duplexers, to advantageously reduce or eliminate some paths and/or components.
Claims14
A wireless architecture comprising a circuit configured to support a first modified time-division duplex (TDD) transmit band and a modified TDD receive band corresponding to the TDD transmit band, the modified TDD transmit and receive bands including an overlapping frequency range, at least one of the modified TDD transmit and receive bands including a non-overlapping frequency range that does not overlap with the other modified TDD band, the circuit including a transmit filter configured to support a transmit operation with at least the modified TDD transmit band, and a receive filter configured to support a receive operation with at least the modified TDD receive band.
A front-end module comprising:
- a packaging substrate configured to receive a plurality of components;
- and
- a radio-frequency circuit implemented on the packaging substrate, and configured to support a modified time-division duplex (TDD) transmit band and a modified TDD receive band corresponding to the TDD transmit band, the modified TDD transmit and receive bands including an overlapping frequency range, at least one of the modified TDD transmit and receive bands including a non-overlapping frequency range that does not overlap with the other modified TDD band, the radio-frequency circuit including a transmit filter configured to support a transmit operation with at least the modified TDD transmit band, and a receive filter configured to support a receive operation with at least the modified TDD receive band.
A wireless device comprising:
- a transceiver configured to process signals;
- an antenna in communication with the transceiver and configured to facilitate transmission of an amplified signal;
- and
- a front-end module in communication with the transceiver and the antenna, the front-end module configured to support a modified time-division duplex (TDD) transmit band and a modified TDD receive band corresponding to the TDD transmit band, the modified TDD transmit and receive bands including an overlapping frequency range, at least one of the modified TDD transmit and receive bands including a non-overlapping frequency range that does not overlap with the other modified TDD band, the front-end module including a transmit filter configured to support a transmit operation with at least the modified TDD transmit band, and a receive filter configured to support a receive operation with at least the modified TDD receive band.
