Abstract: Example access network devices are described. One example access network device includes a signal processing apparatus. The signal processing apparatus includes a first power amplifier, a second power amplifier, a first filter, a second filter, and a combiner. The first filter filters a second signal obtained by the first power amplifier, to obtain a first sub-signal belonging to a first frequency band and a second sub-signal belonging to a second frequency band. The second filter filters a fourth signal obtained by the second power amplifier, to obtain n sub-signals including at least a third sub-signal belonging to a third frequency band. The combiner combines the first sub-signal and i sub-signals in the n sub-signals based on a preset condition, to obtain a first combined signal. The communication module sends the first combined signal by using a first port, and sends the second sub-signal by using a second port.

Abstract: This application provides a resonator that includes a housing and a cover. A resonant rod, a dielectric block, and an elastic element are disposed in the housing. The resonant rod is in a tubular shape and includes an inner side face, an outer side face, and a first end face. The dielectric block includes a bottom end and a top end, the top end is connected to the cover, a second end face and a boss that protrudes from the second end face are disposed at the bottom end, and the boss is in an annular shape. The boss is embedded in the resonant rod a, or the boss fits around the outside of the resonant rod. The elastic element is connected between the first end face and the second end face or between the top end of the dielectric block and the cover.

Abstract: A transverse magnetic (TM) mode dielectric filter includes an enclosure, a dielectric resonator, a main cover, and an elastic component, where the dielectric resonator is disposed in a resonant cavity of the enclosure; the main cover is secured between the elastic component and an open end of the enclosure; the elastic component includes multiple elastic flaps; the multiple elastic flaps are evenly distributed around an axial direction of the dielectric resonator; one end of each of the elastic flaps is fixedly connected to the main cover, and free ends of the elastic flaps elastically act on a central part of an outer surface of the main cover, to provide an elastic force towards the dielectric resonator. The evenly distributed multiple elastic flaps produce a pressure towards the dielectric resonator. A uniform and stable pressure is produced around the dielectric resonator, to ensure a uniform current density inside the resonant cavity.
