According to one embodiment, an amplifier includes a first amplifier with a first output terminal, a second amplifier with a second output terminal, and a plurality of microstrip transmission lines electrically connected to the amplifiers. The transmission lines include an impedance inverter line electrically connected between the first and second output terminals, and an output line electricallyconnected between the second output terminal and an output of the amplifier, where the output line forms a portion of an output impedance transformer. The amplifier also includes a directional couplerformed from a main line and a coupled line positioned in proximity to the main line, where the main line is formed from a portion of one of the transmission lines. The amplifier may also include a module substrate with a plurality of metal layers, where the main line and the coupled line are formed from different portions of the metal layers. 一种放大器的实施例包括具有第一输出端的第一放大器、具有第二输出端的第二放大器以及电连接到所述放大器的多条微带传输线。所述传输线包括电连接在所述第一输出端与所述第
