UWB RF receiver front-end with band-notch characteristic of 5 GHz WLAN

Abstract

This paper proposes a method of realizing band-notch characteristic in the UWB antenna and the low noise amplifier (LNA) such that the UWB RF receiver can fully suppress high-power interference signal in 5 GHz WLAN band. Two procedures of band-notching in RF signal reception are combined, and in fact, such a UWB RF receiver front-end has not been reported yet
