YTLC7924E

YTLC7924E Wi-Fi Filter for LTE (2402.5~2481.5MHz) Description YTLC7924E is a Wi-Fi band filter, which is designed with Film Bulk Acoustic Resonator (FBAR) technology. The product can provide low insertion loss and steep skirt to enables coexistence of Wi-Fi and LTE signals within the same device or in close proximity to one another. The typical insertion loss in the pass band is less than 1.8dB. Typical rejection at the LTE Band 38 and LTE Band 7 and 41 is more than 40dB, at the LTE Band 40 is more than 42dB. For the chip package, the YTLC7924E uses advanced module packing techniques to achieve the industry standard 1.1x0.9x0.6mm footprint, include bumping and flip chip.
