The amplifier operates across the 2 -30 MHz band with relatively flat gaio response and reaches gain saturation at approximately 210 W of output power. Both input and output transformers are 4:1 turns ratio (16:1 impedance ratio) to achieve low input SWRacross the specified band and a high saturation capability.

When using this design, it is important to interconnect the ground plane on the bottom of the board to the top, especially at the emitters of the MRF454s.
