PROBLEM TO BE SOLVED: To provide a radio communication device capable of configuring, by the minimal area, a circuit electrically disconnecting an impedance matching circuit connected with an antenna from a radio communication circuit, and a measurement device of the radio communication device.SOLUTION: In a radio communication device 1, a reactance element 23 is provided by connecting it in series between an input and output end 24a of a radio communication circuit 24 and an impedance matching circuit 22. Furthermore, in a measurement device 3, a measurement reactance element 32 is provided, the reactance element 23 and the measurement reactance element 32 are connected in parallel at a time of power measurement, and a type and a numerical constant of each element are set so that a band rejection filter circuit 4 cutting off a signal at a frequency output from the radio communication circuit 24 will be formed. |
