Problems solved by technology

However, ordinary same-frequency repeaters are limited by the isolation of transceivers, so site selection is difficult, or they cannot work with maximum gain; in order to solve the problem of transceiver isolation, frequency-shift repeaters have been produced; Complicated, ordinary broadband frequency-shifting repeater only directly amplifies all received in-band signals, which is easy to saturate and is not conducive to the optimal use of base stations

Abstract

The invention relates to a frequency selecting and shifting repeater device capable of automatically correcting flatness. The device comprises a near-end machine and a far-end machine, wherein the near-end machine is provided with a donor antenna and a first relay antenna; the far-end machine is provided with a second relay antenna and a cover antenna; the near-end machine receives a signal from a base station through the donor antenna and sends the signal to the far-end machine through the first relay antenna; and the far-end machine receives the signal from the near-end machine through the second relay antenna and sends the signal to a user through the cover antenna. Compared with the prior art, the device has the advantages of reducing production debugging, improving production process capability, having high commonness, avoiding the interference of other systems, and the like.

Description

technical field [0001] The invention relates to a repeater, in particular to a frequency-selective frequency-shifting repeater capable of automatic flatness correction. Background technique [0002] Due to its high cost performance and convenient installation, repeaters are increasingly used in communication networks. However, ordinary same-frequency repeaters are limited by the isolation of transceivers, so site selection is difficult, or they cannot work with maximum gain; in order to solve the problem of transceiver isolation, frequency-shift repeaters have been produced; Complicated, ordinary broadband frequency-shifting repeater only directly amplifies all received in-band signals, which is easy to saturate and is not conducive to the optimal use of base stations. Contents of the invention [0003] The purpose of the present invention is to provide a frequency-selective frequency-shifting direct-frequency shifting device with automatic flatness correction and automat...
