摘要： An apparatus and method for removing an interference signal using a selective frequency phase converter are disclosed. The apparatus for removing an interference signal using a selective frequency phase converter includes: a first phase converter configured to convert a phase of a received RF signal to differentially output first and second signals having a phase difference of 180° from each other; a second phase converter configured to receive the first signal and selectively convert the phase of a particular frequency band; a third phase converter configured to receive the second signal and selectively convert the phase of a particular frequency band; a timing controller configured to correct a signal delay time between the output from the second phase converter and that of the third phase converter; and an adder configured to add an output from the second phase converter and an output from the third phase converter, wherein the second and third phase converters phase-convert the first and second signals such that the phases of the signals of the particular frequency bands do not have a phase difference of 180° from each other.
