This paper presents a dual-band down-conversion mixer with image rejection feature using transformer-coupled notch filter for 2.45-/5.2-GHz WLAN application. A single center-tapped transformer is integrated to form two differential series inductor–capacitor (LC) resonators as a filter circuit to cre...
