RSFD1902C Band25(Band2)FBAR Duplexer

PublishTime：2022-04-25

●Description:
■RSFD1902C is a high performance duplexer designed for applications in LTE Band25 (1350~1915 MHz UL, 1930~1995 MHz DL)and LTE Band 2(1850~1910 MHz UL, 1930~1990 MHz DL)
■RSFD1902C is designed with ROFS's Film Bulk Acoustic Resonator(FBAR)technology, which provides high-Q filters and meets requirements of low insertion loss, high return loss decreases loss at Tx port, high out-of-band attenuation, and excellent isolation between cross band.
■RSFD1902C 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.
