Abstract: RF filter structures are disclosed that may have multiple filter paths, which are provided by weakly coupled resonators. The filter paths may be interconnected so that additional filter paths may be realized between input and output terminals of the RF filter structures. In this manner, the weakly coupled resonators from the filter paths may be arranged in a matrix. In one embodiment, an RF filter structure includes a first filter path and a second filter path. The first filter path includes (at least) a first pair of weakly coupled resonators while a second filter path that includes (at least) a second pair of weakly coupled resonators. To interconnect the first filter path and the second filter path, a cross-coupling capacitive structure is electrically connected between the first filter path and the second filter path. As such, an additional filtering path may be realized through the interconnection provided by the cross-coupling capacitive structure.

Abstract: Power supply circuitry, which includes a parallel amplifier and a parallel amplifier power supply, is disclosed. The power supply circuitry operates in either an average power tracking mode or an envelope tracking mode. The parallel amplifier power supply provides a parallel amplifier power supply signal. The parallel amplifier regulates an envelope power supply voltage based on an envelope power supply control signal using the parallel amplifier power supply signal, which provides power for amplification. During the envelope tracking mode, the envelope power supply voltage at least partially tracks an envelope of an RF transmit signal and the parallel amplifier power supply signal at least partially tracks the envelope power supply control signal. During the average power tracking mode, the envelope power supply voltage does not track the envelope of the RF transmit signal.
