Bandwidth of balanced amplifier can be an octave or more, but is limited by the bandwidth of the coupler.

Bandwidth of balanced amplifier can be an octave or more, but is limited by the bandwidth of the coupler. Correct Answer true

In order to achieve flat gain response, balanced amplifiers use couplers to minimize reflections. But this in turn reduces the bandwidth of the amplifier to the coupler bandwidth.
