PURPOSE: A radio repeater state monitoring apparatus is provided to monitor an operation state of the radio repeater by using a test terminal installed between a base station and a mobile terminal. CONSTITUTION: A radio repeater state monitoring apparatus comprises a multiple of antenna(ANT2,ANT3), directional couplers(12,13), an environment monitoring device(15), an SPDT switch(11), a multiple of duplexors(21,28), and a multiple of path signal amplifiers(22,29). The antenna(ANT2,ANT3) transmits RF signals bidirectionally toward a base station(10) and a mobile terminal(40). The directional couplers(12,13), connected to the antenna(ANT2,ANT3), divides the RF signals into a transmission path and a receiving path. The environment monitoring device(15), installed within the test terminal(14), monitors an internal environment of the repeater. The SPDT switch(11) connects the couplers(12,13) and the test terminal to an active network. The duplexors(21,28) divides the RF signals into a proper transmission/receiving bandwidth.
