Key Front-End Components for W-Band 5G Wireless Backhaul

Abstract:
Fifth generation mobile networks require in the wireless backhaul front-end components capable of covering broader and broader bandwidths, as licensed in W band. The key components of such front-ends are High-Power and Low Noise Amplifiers. The two amplifier types have been realised to cover the full licenced 92 GHz to 115 GHz band, measured results include a minimum of 20dBm with 24 dBm peak output power at 1 dB compression and 17 dB gain for the power stage, while 3.7dB noise figure and 20dB gain are the distinctive performance of the low noise component.
