2_30_MHz_140_W_PEP_AMATEUR_RADIO_LINEAR_AMPLIFIER

He amplifier operates across the 2-30 MHz band with relatively flat gain 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 SWR across 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.
