System for transmitting/receiving multi-band radio frequency signal using dual input, dual output filter

摘要

A system for transmitting/receiving a multi-band Radio Frequency (RF) signal using a Dual Input, Dual Output filter is provided. The system may include a Single-Input Single-Output (SISO) filter and the Dual Input, Dual Output filter. The system for transmitting/receiving a multi-band Radio Frequency (RF) may be implemented in a Radio Frequency (RF) region, which includes an area from an end of an antenna to an end of a mixer in a mobile communication.
