Systems, methods, and apparatus are disclosed for wideband power amplification in a platform, such as an airplane. An amplifier module may include a first amplification stage. The first amplification stage may comprise a first plurality of amplification circuits. The amplifier module may also include a first plurality of couplers configured to couple an input port to each amplification circuit of the first amplification stage. The amplifier module may include a second amplification stage comprising a second plurality of amplification circuits. The amplifier module may also include a second plurality of couplers configured to couple the first amplification stage to the second amplification stage. The amplifier module may include a third plurality of couplers configured to combine an output of each amplification circuit of the second plurality of amplification circuits into an output signal. The third plurality of couplers may comprise one or more Lange couplers.
