    Abstract: A method of detecting a synchronization switching pulse using a power detector in a time division duplexing (TDD) system includes receiving an input signal, detecting a power level associated with the input signal using a digital power meter, and determining a configuration associated with the input signal. The method also includes determining that a pulse width associated with the input signal is greater than a threshold, determining an offset associated with a special subframe configuration, and generating an estimated sync pulse. The method further includes forming a regenerated sync pulse, determining an error between the estimated sync pulse and the regenerated sync pulse, determining that the error is less than a threshold, and providing a lock detect.

    Abstract: A power amplifier using N-way Doherty structure with adaptive bias supply power tracking for extending the efficiency region over the high peak-to-average power ratio of the multiplexing modulated signals such as wideband code division multiple access and orthogonal frequency division multiplexing is disclosed. In an embodiment, present invention uses a dual-feed distributed structure to an N-way Doherty amplifier to improve the isolation between at least one main amplifier and at least one peaking amplifier and, and also to improve both gain and efficiency performance at high output back-off power. Hybrid couplers can be used at either or both of the input and output. In at least some implementations, circuit space is also conserved due to the integration of amplification, power splitting and combining.
