Brief description of the drawings
Fig. 1 is the structural representation of the multiplexing active antenna of a kind of passage frequency conversion of the utility model.
Number in the figure is described as follows: the active frequency conversion front end of 1-, and 11-main frame, the active dual polarized antenna of 2-, 21-slave, 22-antenna, 3-frequency conversion amplifier, 4-mixer, 5-is with line feed system.
Embodiment
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment.
As shown in Figure 1, the multiplexing active antenna of a kind of passage frequency conversion of the present utility model, comprises successively the active frequency conversion front end 1 of main frame that connects, the active dual polarized antenna 2 of slave and with line feed system 5.
The active frequency conversion front end 1 of main frame comprises main frame 11, frequency conversion amplifier 3 and mixer 4,
The active dual polarized antenna 2 of slave comprises slave 21, frequency conversion amplifier 3 and dual polarized antenna 22, slave 21, frequency conversion amplifier 3 and dual polarized antenna 22 are Integration Design, for ensureing phase noise and the frequency stability requirement of system, each active dual polarized antenna equipment all needs to be equipped with highly stable frequency reference signal, ensure to meet the demands in certain temperature range
Comprise electrical source of power, overcurrent coupler and overcurrent mixer with line feed system 5, adopt coaxial distribution cable feeding classification to realize and power with road.
Operation principle: frequency conversion system is by for example, carrying out frequency conversion to a channel signal of TD-LTE source device (LTE RRU), realize and the isolation of another one LTE passage in frequency, two paths of signals can close road mode by frequency and realizes in the antenna-feedback system of Yi road and transmitting like this, reaches the object of TD-LTE stream transmission.
Frequency conversion system is realized two-way power error within 2dB by accurate power control techniques, has ensured preferably power-balance; By adopting frequency conversion system, Jin Yong mono-road compartment system can be realized TD-LTE double fluid technical scheme, has solved preferably the particular problem of the engineered difficulty of chamber subsystem; Owing to only having a wherein road signal to transmit through active frequency conversion in two-way LET signal, an other road still adopts whole passive compartment system transmission, under active equipment failure condition, still can ensure that like this this road signal normally works, ensure basic LTE one-channel signal coverage requirement.
The utility model had both solved indoor dual polarized antenna need to take into account other system and close the bandwidth difficult problem on road, has solved again the construction difficult problem that increases antenna point in the system reform, will greatly promote construction and the application of following indoor LTE system.
Embodiment recited above is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model, all should fall in the definite protection range of claims of the present utility model.
