PURPOSE: A duplexer filter using transmission path distribution is provided to simultaneously implement transceiving diversity with a duplexer filter by distributing an RF signal into two transmission paths. CONSTITUTION: A duplexer filter using transmission path distribution comprises a first receiving BPF(band pass filter,11), a second receiving BPF(12) and a transmission BPF(13). The first receiving BPF(11) passes a particular receiving frequency band of an RF signal from a first receiving path. The second receiving BPF(12) passes a particular receiving frequency band of an RF signal from a second receiving path. The transmission BPF(13) distributes the RF signal into two transmission paths to output from a first and a second transmission paths by passing a particular transmission frequency band of an input RF signal and performing simultaneous magnetic induction of two resonators sequentially.
