  • Decade bandwidth planar MMIC four port transformer
    Patent number: 8362835
    Abstract: A wide bandwidth planar four port MMIC transformer is provided by input diplexers which divide up the incoming signal into a high band and a low band, with the resulting signals coupled to high band and low band four port transformers implemented in one embodiment using spiral inductors and coupled lines, the outputs of which are combined using two output diplexers to provide a decade bandwidth transformer.
