Abstract
A concurrent matching network using transmission lines for low loss is disclosed. In an exemplary embodiment, an apparatus includes a first ¼ wavelength transmission line configured to couple a first signal path to a common node that is coupled to one or more additional signal paths. The apparatus also includes at least one switch configured to disable the first signal path causing the first ¼ wavelength transmission line to provide a first off-state impedance at the common node.

An apparatus comprising:
- a first ¼ wavelength transmission line configured to couple a first signal path to a common node that is coupled to one or more additional signal paths;
- and
- at least one switch configured to disable the first signal path causing the first ¼ wavelength transmission line to provide a first off-state impedance at the common node.
An apparatus comprising:
- means for providing a first ¼ wavelength transmission path configured to couple a first signal path to a common node that is coupled to one or more additional signal paths;
- and
- means for switching configured to disable the first signal path causing the means for providing a first ¼ wavelength transmission path to provide a first off-state impedance at the common node.
