Embodiment 1
[0044]Such as Figure 1-7 As shown, the present invention provides a radio frequency matrix, and the radio frequency matrix is an M×N radio frequency matrix; it includes M first ports and N second ports, and each first port is connected to a one-point N power division / combination The main port of the router, each second port is connected to the main port of a one-point M power divider / combiner, one branch port of each one-point N power divider / combiner and each one-point M power divider A phase-shifting module is connected between one port of the combiner / combiner to form a radio frequency channel, wherein the power divider / combiner can combine multiple signals into one, or divide one signal into multiple signals.
[0045] One-point-N power divider / combiner is used to divide one original signal transmitted by one first port into N-way signals and transmit them to one branch port of each one-point M power divider / combiner, or divide each one-point M The N channels of origina...
Embodiment 2
[0080] A test system includes a control device, the M×N radio frequency matrix in Embodiment 1, a power supply system and a chassis frame.
[0081] The control device is connected to the M×N radio frequency matrix, and the control device is used to obtain a target beam angle, and obtain each of the M×N uplink channels and the M×N downlink channels according to the target beam angle and a preset model. The phase setting value of each channel, and adjust the phase shifting and attenuation module or the phase value of the phase shifting module of the corresponding channel according to the phase setting value of each channel.
[0082] The M×N radio frequency matrix includes an M×N radio frequency matrix, and the M×N radio frequency matrix includes M first ports and N second ports. M first ports are connected to the base station, N second ports are connected to the terminal, the base station sends out M original signals, and the M×N radio frequency matrix receives the M original si...
Embodiment 3
[0102] see figure 2 , on the basis of the second embodiment, add N attenuation modules at the positions of N second ports, and at this time, the M×N radio frequency matrix includes M×N×2 phase-shifting modules and N attenuating modules.
[0103] At this time, the control device is also used to obtain the target gain, and adjust the attenuation value of the corresponding attenuation module in real time according to the target gain.
[0104] When the system is in use, the attenuation value of the corresponding attenuation module can also be manually adjusted according to the target gain until the target gain is reached.
