Abstract
Wide-band matching in out-of-band blocker rejection filters is provided. A device includes a first inductor. The device includes a second inductor magnetically coupled with the first inductor and with an amplifier. The device includes a notch filter electrically coupled between the first inductor and the second inductor. The amplifier can be configured to amplify a plurality of radio frequency signals. A bandwidth of the radio frequency signals can exceed 1.5 gigahertz (GHz).
