Title:
COUPLING DEVICE, SIGNAL EQUALIZATION METHOD AND INDOOR DISTRIBUTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/231406
Kind Code:
A1
Abstract:
The present disclosure provides a coupling device, a signal equalization method and an indoor distribution system, and relates to the technical field of wireless communications. The coupling device comprises: a four-port coupler comprising an input port, a coupling port, an output port, an isolation port and a system coupling port, and configured to perform power equalization processing on an input signal, wherein the input signal comprises a coupling signal and a through connect signal; a low-noise amplifier unit connected between the coupling port and the system coupling port and configured to perform signal amplification processing on the coupling signal; and an energy conversion unit, wherein two ends of the energy conversion unit are respectively connected to the isolation port and the low-noise amplifier unit, and the energy conversion unit is configured to convert a radio frequency signal of the isolation port into electric energy to provide electric energy for the low-noise amplifier unit. According to the coupling device, reverse insertion loss of the coupling device is reduced, the uplink noise coefficient is reduced, and the uplink performance is improved.
