YTLD1702C

YTLD1702C Band3 FBAR Duplexer Description YTLD1702C is a high performance duplexer designed for applications in LTE Band 3 (1710 – 1785 MHz UL, 1805 – 1880 MHz DL). YTLD1702C is designed with Film Bulk Acoustic Resonator (FBAR) technology, which provides high-Q filters and meet requirements of low insertion loss, high out-of-band attenuation, high power handling and stringent linearity. YTLD1702C uses chip scale packaging (CSP) technology to assembly the filters into a molded chip-on-board module with the footprint of 1.8mm x 1.4mm and height of 0.61mm.
