Abstract
An amplifier device having an extended bandwidth includes a DC coupled amplifier and multiple low noise amplifiers connected in series with one another and connected in parallel with at least a portion of the DC coupled amplifier. The DC coupled amplifier has a broad bandwidth, and each of the low noise amplifiers has a narrow bandwidth and a center frequency higher than a high end frequency of the broad bandwidth of the DC coupled amplifier. The extended bandwidth of the amplifier device is a combination of the broad bandwidth and the first narrow bandwidth.
