ROFS-RSFP2312E
RSFP2312E  
LTE Band 40(2300~2400MHz) Band Pass Filter  
Description  
RSFP2312E is a miniature filter designed for LTE Band40 application.  
RSFP2312E is designed with Film Bulk Acoustic Resonator (FBAR)  
technology. Typical insertion loss in the pass band is less than 2.4dB. Typical  
rejection at the WiFi and LTE41 band are more than 35dB.
