PROBLEM TO BE SOLVED: To provide a transceiver reducing cost of a transmitting/receiving device and improving the reliability thereof by reducing damages on a transmission amplifier part. SOLUTION: This transceiver 100 includes: the transmission amplifier part 1 for amplifying a transmission signal (f1); an antenna 3 for radiating the transmission signal (f1) amplified by the transmission amplifier part 1, as radio waves and receiving reception radio waves as a reception signal (f2); a transmission/reception separating circulator 2 for separating the transmission signal (f1) to be transmitted from the antenna 3 from the received reception signal (f2); a band removal filter 6 for removing an unnecessary band signal included in the reception signal (f2), separated by the transmission/reception separating circulator 2; a reception amplifier part 7 for amplifying the reception signal (f2) having passed through the band removal filter 6; and an antireflective circulator (isolator) 4 for transmitting an undesired signal (fx) reflected from the band removal filter 6 to a reflected wave-absorbing terminator 5.
