Fractional bandwidth is the bandwidth of a device divided by its center frequency. E.g., a passband filter that has a bandwidth of 3MHz with center frequency 8 MHz will have a fractional bandwidth of 3/8.

Wideband doherty power amplifier
A broadband Doherty power amplifier is disclosed. The Doherty power amplifier includes a main power amplifier and a peak amplifier. Compared to the conventional method of combining the outputs of the main and peak amplifiers before an impedance transformation circuit, this Doherty power amplifier combines the outputs after an impedance transformation circuit in the peak amplifier output path. This eliminates or at least reduces the possible impedance step drop and corresponding impedance step rise for the main output path. This reduction or elimination of the step drop and rise reduces insertion loss and allows for increased efficiency at the first efficiency peak, thus improving the fractional bandwidth of the Doherty power amplifier.
