Abstract
The invention relates to a medium combiner which comprises a plurality of medium filters 1, 2 until n for filtering different frequency bands and a plurality of signal channels 1, 2 until m, wherein signals at the same frequency band in the signal channels 1, 2 until m pass the corresponding same medium filter. According to the medium combiner disclosed by the invention, the signals at the same frequency band in different signal channels are processed by the same medium filter, so that the traditional one-to-one or one-to-many structural form of the signal channels and the medium filters is changed into a many-to-one structural form; by adopting the structural form, the space of the combiner and signal wires are saved and the utilization rate of the signal wires is increased.
Description
Technical field
The present invention relates to a kind of medium mixer, belong to the communicator technical field.
Background technology
In engineering is used, the C net of 800MHZ and two kinds of frequencies of G net of 900MHz need to be closed road output.Adopt mixer, can make a cover indoor distributed system work in simultaneously CDMA frequency range and GSM frequency range.And for example in radio antenna system, after (such as 145MHZ and 435MHZ) input/output signals of several different frequency ranges closed the road by mixer, be connected with the radio station with a feeder line, this has not only saved a feeder line, has also avoided switching the trouble of different antennae.
Need to prove in mixer is used in addition, base station or repeater signal feed-in mode are wireless, and its information source is wide spectrum, therefore requires narrow passband in some occasion, to guarantee the pure of signal; The signal feed-in mode of mixer is cable, and signal is directly taken from information source, and its information source is narrow spectrum signal.Such as mixer CDMA/GSM passage, channel width is 800-960MHz, and when a GSM CF signal of access, because information source is a CF signal, the feed-in mode is cable, only has this CF signal in the passage, does not have other interference signal.Therefore the design of the fat pipe of mixer is feasible in actual applications.
Its version of existing mixer is: the corresponding corresponding dielectric filter of one tunnel signalling channel or corresponding a plurality of dielectric filter are isolated from each other through before the filter; Such as corresponding dielectric filter, owing to may comprise the signal of different frequency range in one tunnel signalling channel, in the dielectric filter filtering, be difficult to the complete whole filterings of signal with institute's filtering, and keep required signal like this; Such as a plurality of dielectric filters of correspondence, the utilization ratio of each dielectric filter is low, occupies more space, and holding wire is laid comparatively loaded down with trivial details.
Summary of the invention
The present invention is directed to defects, purpose is to provide a kind of signal utilance that provides, and saves the medium mixer of space and holding wire.
The technical solution used in the present invention is for this reason: the present invention comprise a plurality of filtration different frequency ranges dielectric filter 1,2 ... n, many barss passage 1,2 ... m, described signalling channel 1,2 ... same frequency band signals among the m is by corresponding same dielectric filter.
Advantage of the present invention is: the present invention processes the signal of unlike signal passage similar frequency bands by same dielectric filter, classical signal passage and dielectric filter have been changed one to one or the version of one-to-many, become many-to-one version, this kind version has been saved space and the holding wire of mixer, has improved the utilance of holding wire.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of traditional mixer.
Embodiment
Take Fig. 1 as example, the present invention comprises four frequency ranges: the logical dielectric filter 1,2,3,4 of band.Wherein dielectric filter 3 passes through signal at channel C H1 on the CH2.Channel C H1 own, CH2 be the signal by self dielectric filter also.Its result is merged into three road signals to four road signals, has saved space and holding wire, has improved the holding wire utilance.
Claims (1)
1. the medium mixer is characterized in that, comprise a plurality of filtration different frequency ranges dielectric filter 1,2 ... n, many barss passage 1,2 ... m, described signalling channel 1,2 ... same frequency band signals among the m is by corresponding same dielectric filter.
