Abstract

A duplex filter device, an RRU system and a wireless radio frequency system, wherein the duplex filter device includes at least one filter unit, one end of a transceiver combiner and a first group consisting of at least one receive filter and a transmit filter One end of the filter is respectively connected to the first ANT; the other end of the transceiver combiner and one end of the second group of filters composed of at least one receiving filter and a transmitting filter are respectively connected to the second ANT, wherein the ANT is connected to the second ANT connected to the external interface unit; and connected to the external interface unit through ANT; the receiving filter in the first group of filters and the second group of filters is connected to the remote radio unit RRU through the input port RX; the first group of filters and the second The transmit filter in the bank filter is connected to the RRU through the output port TX. The present invention solves the problems in the related art that the network structure of the duplex filter and its system is complex and the number of cables is too large.

Description

technical field [0001] The present invention relates to the radio frequency field, in particular to a duplex filter device, an RRU system and a wireless radio frequency system. Background technique [0002] In the related art, a duplex filter radio frequency device includes a transmit filter and a receive filter to form a main collector and transmit duplexer, and a single filter to form a diversity receive filter. Usually the transmit filter and receive filter of the duplexer are composed of metal coaxial cavity. In order to meet the performance of transceiver suppression and insertion loss required by the base station, transmit filter and receive filter Each device is composed of multiple metal resonators. [0003] figure 1 It is a schematic diagram of a duplex filter and its system networking architecture in the related art, such as figure 1 As shown, it consists of two Radio Remote Units (RRU for short), four inter-frequency combiners, a four-port antenna and multiple ...
