Abstract:
An apparatus is disclosed including a tunable passive phase shifter. In example implementations, a phase shifter reuses one or more inductors for multiple bands and can reduce switch use along a propagation path to lower insertion loss. In an example aspect, an apparatus for phase shifting includes a phase shifter having a first port and a second port. The phase shifter includes an inductive path, which is coupled between the first and second ports, and first and second bypass paths. The inductive path includes multiple inductors and multiple nodes. The multiple inductors are coupled together in series between the first and second ports. The multiple nodes are interleaved with the multiple inductors along the inductive path. The first bypass path is coupled to a first pair of nodes of the multiple nodes, and the second bypass path is coupled to a second pair of nodes of the multiple nodes.
