Design of Broadband High Power Amplifier Based on Odd Equal Power

In this paper, a solid-state powder amplifier with a coverage frequency range of 6∼18GHz is designed. Aiming at the amplifier's high power synthesis design, an odd-equip planar circuit synthesis method is proposed. That is, the power output of 12 GaN ways exceeding 10W is realized by using two-to-one micro-stripe circuit and six to one micro-stripe to achieve continuous wave power output above 70W, of which six odd circuits use multi-stage gradient non-isolated resistance design. The experimental results show that the highest synthesis efficiency is 85% and the maximum output power is over 120W, which meets the design requirements. The design of the power amplifier plays a key role in increasing the effective radiation power of the electromagnetic transmitting system based on multi-beam system.
