TRANSMISSION/RECEPTION DEVICE

摘要

Provided is a transmission/reception device which can be simultaneously operated in a plurality of radio systems. The transmission/reception device includes: a first communication circuit (1a) corresponding to a first radio system; a second communication circuit (1b) corresponding to a second radio system; an oscillator (2) which generates a common frequency signal shared by the first communication circuit (1a) and the second communication circuit (1b); and frequency converters (3a, 3b) which frequency-convert the common frequency signal generated by the oscillator (2) and supply a local signal to the first communication circuit (1a) or the second communication circuit (1b).
