5G Conducted MIMO Test System

5G wireless communication technology uses massive MIMO technology, which puts forward higher requirements for base station and terminal RF and performance testing. At present, the RF and antenna ports of the sub 6G base station can be separated from the structure, and the base station can pass the conduction test. Before 5G, the base station RF index test mostly adopts conduction test method, but in 5G era, due to the application of massive MIMO technology, the complexity of conduction test increases greatly, and conduction test fully characterizes the base station RF performance. Conduction test is the use of RF cable directly connect the instrument and the object to be tested together, to avoid the impact of space radiation interference signal on the test. HBTE has the ability to build 5G end-to-end test environment. The following describes the test solution.


HBTE provides programmable phase-shifting attenuation matrix solution and fixed phase shifter and programmable attenuation matrix solution.


Programmable phase-shift attenuation matrix solution


Programmable phase-shifting attenuation matrix supports arbitrary adjustment of signal attenuation phase. The attenuation adjustment range is 0-90db, the attenuation step is 0.5dB, the phase adjustment range is 0-360 ° and the phase step is 2.8 ° and 1 ° respectively. This system can also add a channel simulator before ue to simulate the characteristics of wireless channels, including path loss, multipath fading, delay spread, Doppler spread, polarization, and correlation and spatial parameters that are crucial to the performance of MIMO and multi wireless systems.

Fixed phase shifter and programmable attenuation matrix solution


The fixed phase shift matrix can provide fixed phase angle relationship, and the programmable attenuator matrix can provide 0-63db attenuation range. This system can also add a channel simulator before ue to simulate the characteristics of wireless channels, including path loss, multipath fading, delay spread, Doppler spread, polarization, and correlation and spatial parameters that are crucial to the performance of MIMO and multi wireless systems.
