Abstract :
USB3 devices use 5-Gbps signalling and the data spectrum can generate broadband noise in the 2.4-GHz ISM band. The noise can radiate from the USB3 connectors or cables and cause radio frequency interference (RFI) to a wireless receiver whose antenna is placed near a USB3 device. In this paper the root-cause for the radiation from USB3 receptacle connectors is presented. Simulation and measurement data are shown on an improved connector design that can reduce the amount of noise radiated.
