The invention discloses a monolithic microwave integrated circuit of an ultra-wideband reconfigurable power amplifier. The monolithic microwave integrated circuit comprises a control power amplifier unit, a balance power amplifier unit, an ultra-wideband phase shift network, a first ultra-wideband coupler, a second ultra-wideband coupler and a third ultra-wideband coupler. The balanced power amplifier unit comprises two mirror-image power amplifier units, the output power of the power amplifier units is controlled to carry out active load modulation on the load impedance of the two power amplifier units in the balanced power amplifier unit, and ultra-wideband reconfiguration is realized. 本发明公开了一种超宽带可重构功率放大器单片微波集成电路，包括控制功放单元、平衡功放单元、超宽带移相网络以及第一～第三超宽带耦合器。所述平衡功放单元包括镜像的两个功放单元，控制功放单元的输出功率对平衡功放单元中的两个功放单元的负载阻抗进行有源负载调制，实现超宽带可重构。
