We report microwave and temporal measurements on nonlinear transport in GaInAs/AlInAs superlattice n + n -n + diodes. The superlattices have wide minibands, wider than 80 meV. The microwave experiments are performed for 0-65 GHz. The diodes exhibit reflection gain up to 65 GHz over a bias-dependent
