| Abstract: | With the rapid construction of 5G commercial network,there is a lot of vacancy in domestic 5G network test equipment.A 3.5 GHz dual-channel radio frequency(RF) front-end for 5G terminal simulator is designed.This RF front-end with ADRV9009 chip supports dual-channel RF transceiver at the same time,and it is featured by fewer devices and lower design complexity.The experimental results show that the RF front-end has stable performance,the receiving sensitivity is -85 dBm and noise figure is less than 2.6 dB,error vector magnitude of the transmitted signal at 256QAM modulation is 1.43%,which has achieved the design requirements of 5G terminal simulator. |
