5G Testbed for 57-65 GHz
Future wireless communication systems will use higher frequency bands to circumvent the spectral shortage at lower frequencies. Our testbed is used to study the propagation conditions in the V-band.
The signals from our 4 channel arbitrary waveform generator (AWG) Keysight M8195 are up converted using off-the-self (802.11ad) moduls.
The waveform generator is used either as baseband transmitter in data transmission scenarios or as sounding sequence generator in channel measurements.
The arbitrary waveform generator is capable of directly producing signal with frequency content of up to 32 GHz.
The spectrum analyser can be used as general purpose 2 GHz bandwidth receiver. The IQ analyzer option and a real time oscilloscope are used for this purpose.
The AWG together with our mmW modules and the FSW can be used as testbed for 60 GHz signals of bandwidths of up to 2 GHz.
