5g new scheme! Upgrade the existing base station and UE simulator to 5g millimeter wave band

     Today we are going to introduce sub-6GHz Simulator with beamformer and rainbow / The down converter is used in combination without any additional noise , So as to extend it to 5G Millimeter wave band .

present situation

●

     Signaling communication test is the research of telecommunication 、 The core of baseband and base station design , The base station simulator can be tested without the actual base station , So as to save cost and time . With 5G More and more communication has been extended to the field of millimeter wave design and development ,5G Developers and designers must find more cost-effective ways .

    UE Simulator solutions enable baseband researchers 、 Telecom operators 、 Chipset providers and infrastructure providers can verify end-to-end wireless network performance by simulating real network behavior and traffic .

     Hongke with beam forming equipment / Downconverter TMYTEK UD Box 5G To be able to sub-6GHz The simulator is extended to 5G Millimeter wave band . The beam forming equipment generates a signal beam , This beam is generated by UD Box 5G On going / Down conversion , Thus, the base station and UE The simulator is upgraded to millimeter wave version , Make it have 3GPP The standard defines the signaling communication test for functional verification 、 High throughput performance testing capability , It can be applied to millimeter wave terminal function verification and performance test , And from PHY To RRC/NAS Layer of 5G analysis .

advantage

take sub-6GHz The simulator is extended to 5G Millimeter wave band

Easy up and down conversion in one box

5G Millimeter wave system / Communication design and development tools

     Hongke Shang / Downconverter TMYTEK UD Box 5G It is an ultra wideband 5G NR Millimeter wave frequency converter , Coverage up to 44GHz. It comes with an integrated mixer 、 Inside LO And optional if and RF filters , Dedicated to 5G And satellite communications .

Number of RF channels	1/2
Radio frequency	24-44GHz
If frequency	0.01-14GHz
Local frequency	24-44GHz
Local frequency resolution	0.01MHz

Simulator test architecture

     For the test setup shown in the figure , be based on Amarisoft SDR Of UE Simulator and Hongke dual channel / The down converter is used together ,UD Box 5G Convert high-frequency millimeter wave signal into RF, The RF is fed back to HPF. This test shows that the existing sub-6GHz Simulator for 5G Millimeter wave capability .

     The RF signal is provided by Hongke TMYTEK UD Box 5G Down convert to lower if signal , Then it is input SDR Intermediate processing , Output IF Be activated .

The actual test setup

     The test settings are shown in the figure , Include SDR、 Siphonaceae TMYTEK UD Box 5G And control PC.

test result

     For frequencies up to 43GHz The comparison of the results shows that , Hongke Shang / The down converter will not add any additional noise , So in all cases ,EVM Values are kept at the same level .
