Features

that utilize high data rates simultaneously, removing interference within wireless terminals like handsets has become a challenge. Reducing the Electromagnetic Interference recovers the receiver sensitivity, enabling simultaneous operation of multiple radios, and improves the overall quality of service of communication devices. Intersil’s QHx220 is situated in a handset to sample the source of the noise and emulate the RF coupling channel between the noise source and victim receiver antenna. In.
