  • Filter of repeater for mobile communication system
    Patent number: 9887713
    Abstract: Provided is an intermediate frequency (IF) filter of a repeater for a mobile communication system that enables the use of a normal cyclic prefix (CP) of 4.7 usec as much as possible by minimizing a delay caused by the IF filter of a radio frequency (RF) repeater for the mobile communication system, such as a long-term evolution (LTE) orthogonal frequency-division multiple access (OFDMA) system.
    Type: Grant
