What is wideband amplifier?

A wideband amplifier is an electronic circuit providing constant amplification with a ratio of its low corner frequency to its high corner frequency of more than an octave.

The widwband amplifier is complementary in concept to "audio amplifier" (20Hz-20KHz) and "video amplifier" (15KHz to 4.8MHZ).

The "opposite" concept is the narrow-band or tuned amplifier.

There's a new wideband amplifier technology called PowerBand from TriQuint Semiconductor.
