description PROBLEM TO BE SOLVED: To provide a communication device having a simple circuit configuration suppressing a consumption power and containing a wide-band transmission amplifier preventing the deterioration of a communication propagated distance. SOLUTION: The communication device contains an amplifier 101 adjusting a transmission power for a first signal and the transmission power for a second signal when the transmission power for the first signal comprised in a first frequency band and having a first frequency and the transmission power for the second signal comprised in a second frequency band different from the first frequency band and having a second frequency different from the first frequency differ. The amplifier 101 has a variable inductor 110 adjusting the transmission power for the first signal and the transmission power for the second signal by changing an inductance value to each of the first signal and the second signal.
