摘要
A concurrent-type multiband amplifier (or a dual-band amplifier) which amplifies multiband signals concurrently using a plurality of (N) amplifier circuits which each independently amplify signals in a plurality of (N) frequency bands. An n-th (n=any of 1 to N) amplifier circuit is provided with a circuit for blocking signals in frequency bands other than the n-th frequency band so as to amplify and output only the n-th frequency band signal. The n-th amplifier circuit is designed so as to consist of its input/output impedance matching circuit for the n-th an amplifier element at the n-th frequency band.
