This paper presents a LTE receiver front-end with a feedback digital filter in the baseband to perform multiband blocker cancellation. The programmable filter provides 34.9dB attenuation of TX leakage and variable attenuation of an additional blocker anywhere in the frequency range 17.5MHz-107.5MHz. The receiver front-end operates at 1.8GHz with a noise figure of 3.9dB, IIP3 of -5dBm, and consumes only 20.4-37.5mW, the lowest among state-of-the-art designs.

Abstract
This paper presents a LTE receiver front-end with a feedback digital filter in the baseband to perform multiband blocker cancellation. The programmable filter provides 34.9dB attenuation of TX leakage and variable attenuation of an additional blocker anywhere in the frequency range 17.5MHz-107.5MHz. The receiver front-end operates at 1.8GHz with a noise figure of 3.9dB, IIP3 of -5dBm, and consumes only 20.4-37.5mW, the lowest among state-of-the-art designs.File in questo prodotto:
