YTLD2503C

YTLD2503C Band7 BAW Duplexer Description YTLD2503C is a high performance duplexer designed for applications in LTE Band7 (2500~2570 MHz UL, 2620~2690 MHz DL). YTLD2503C is designed with ROFS’s MEMS BAW technology, which provides high Q filters and firstclass reliability. Low insertion loss and return loss of Tx port reduce the current from power amplifier. High out-of-band attenuation in the Wi-Fi band coexist with Wi-Fi signal under working condition. High isolation of Rx port improve sensitivity in the receive band . YTLD2503C 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.
