  • Patent number: 11217871
    Abstract: A distributor and a synthesizer with low loss are disclosed. In one example, a distributor/synthesizer has a distribution line that distributes a path from an input branch unit connected to an external transmission line on an input side into n-distributed paths. An output branch unit divides the n-distributed paths into an internal side and an external transmission line on an output side. On the internal side, a phase adjustment unit is arranged between the output branch unit and a coupling terminal, and adjusts the phase. A phase rotation amount from the input branch unit to the output branch unit of each of the n-distributed paths is ?/2 [rad], and a phase rotation amount from the output branch unit to the coupling terminal is ? [rad] or a real number multiple of ? [rad]. The present disclosure can, for example, be applied to an FEM of a signal processing device.
