When the high-speed TDD switch is switched to a downlink radio frequency channel (i.e., in a downlink transmission timeslot), a radio frequency signal transmitted by the radio frequency remote unit is transmitted to each radiation unit 20 of the antenna array 16 through the coupling calibration plate 14 (for performing zero calibration on the difference loss and phase of the radio frequency signal to realize wave speed shaping), the power divider 15, and the integrated intelligent amplification unit 13 (through the high-speed TDD switch), and radiated to form antenna directional coverage;

The following describes the components of the active 5G-iLAN smart antenna of the present invention:
in the embodiment of the present invention, the integrated intelligent amplification unit 13 is 20 integrated intelligent amplification units 13, the number of the integrated intelligent amplification units 13 is 2, the integrated intelligent amplification unit 13 is a dual-cavity structure, a CPU control board is disposed in the dual-cavity structure, 10 TDD/LAN boards are disposed in each of an upper cavity and a lower cavity of the dual-cavity structure, and an opening is disposed in the middle of the dual-cavity structure for connecting the TDD/LAN board of the upper cavity and the TDD/LAN board of the lower cavity.
Specifically, referring to fig. 2, the integrated intelligent amplification unit 13 further includes: TDD/LAN board, CPU control panel, SMA joint, the radio frequency cable of label 1-20 and the radio frequency cable of label 1A-5D. 20 TDD/LAN board has constituted 20 way radio frequency channels, and input, output radio frequency cable are RG141 cable, and the CPU control panel includes: modulation/demodulation circuit (for lightning protection), LAN alarm monitoring circuit and gain control circuit. The power supply, the TDD synchronous control signal and the RS-232 communication signal (adjustment gain or monitoring) of the integrated intelligent amplification unit 13 during operation are transmitted in a modulated OOK signal format, and are connected to the SMA connector through the radio frequency cable, so as to ensure that the lightning protection characteristics meet the requirements.
Referring to fig. 3, the integrated intelligent amplifying unit 13 has a dual-cavity structure (only one cavity is shown in fig. 3, and the same cavity is also arranged right below the integrated intelligent amplifying unit, and the two cavities are called as an upper cavity and a lower cavity), 10 TDD/LAN boards are respectively placed in the upper and lower cavities, an opening is formed in the middle of the cavity (which can be a rectangular space) for transmitting control signals of the upper and lower cavities, a welding protection platform is arranged at the position where the RG141 radio frequency cable is welded outside the cavity, the whole cavity is plated with tin to ensure stable and reliable welding of the cable, and upper and lower covers of the cavity are reliably connected with the cavity through screws to ensure sealing and shielding to meet requirements.
In addition, each path of the TDD/LAN board includes: high speed TDD switches (which may be high speed PIN switches in particular), LAN low noise amplifiers, filters and circulators. The high-speed TDD switch is controlled by the TDD synchronization control signal to switch the radio frequency channel, as shown in fig. 4, the high-speed TDD switch turns to the A1a2 channel at the transmission timeslot, and the downlink radio frequency signal is directly communicated to the radiation unit 20 of the antenna array 16; when the receiving time slot high-speed TDD switch is switched to the B2B1 channel, the uplink radio frequency signal received by the radiating unit 20 passes through the LAN low noise amplifier (triangle in fig. 4) and then reaches the RRU.
The advantages of the integrated intelligent amplification unit 13 of the utility model are explained below: when the problem of imbalance of uplink and downlink of a passive antenna is solved, a scheme is that an LAN low noise amplifier is additionally arranged outside an antenna radio frequency port 17 (namely, an external LAN low noise amplifier is arranged between the antenna radio frequency port 17 and an RRU), and the scheme cannot effectively improve the signal-to-noise ratio and effectively solve the problem of imbalance of the uplink and downlink; another solution is to independently connect a LAN low noise amplifier (or called as a radio frequency amplification component, that is, a LAN low noise amplifier is independently arranged for each radiation unit 20) behind each radiation unit 20 inside the antenna, which can improve the signal-to-noise ratio, but because the LAN low noise amplifier needs to be independently arranged for each radiation unit 20, the wiring is complicated, the cost is high, and the fault monitoring and management of the LAN low noise amplifier cannot be realized, and if the fault monitoring and management of the LAN low noise amplifier needs to be realized, a plurality of CPU control boards need to be correspondingly arranged, obviously, the cost is greatly increased. Based on this, the inventor designs the integrated intelligent amplifying unit 13, each integrated intelligent amplifying unit 13 integrates 20 TDD/LAN boards (which can amplify the synthesized uplink signal of each antenna radiating unit 20), simplifies the wiring, and only needs to set one CPU control board to realize the fault monitoring and management of 20 LAN low noise amplifiers on the 20 TDD/LAN boards, which also saves the cost and simultaneously achieves the purpose of effectively improving the signal-to-noise ratio.
The distributed active 5G-iLAN smart antenna of the present invention employs a dual polarized antenna array 16, each polarization representing a radio frequency channel, for a total of 8 identical radio frequency channels. The following describes the flow of the single-channel rf signal of the active 5G-iLAN smart antenna of the present invention: as shown in fig. 5 (a flow chart of single-channel radio frequency signals), when the downlink works, the RRU downlink signal is power-divided by the 5-way power divider 15 to form 5-way radio frequency signals, i.e., 1-1, 1-2, 1-3, 1-4, and 1-5, and the radio frequency signals are respectively directly transmitted through the TDD/LAN board to the 1A, 2A, 3A, 4A, and 5 A5 radiation units 20 to form a directional emission directional diagram; during uplink work, signals received by the radiation units 201A, 2A, 3A, 4A, and 5A are amplified by the LAN low noise amplifier, and synthesized by the power divider 15 to reach the RRU.
