Abstract: Methods and devices to minimize or reduce phase discontinuity between different gain modes (including bypass, active and passive modes) with reduced increase in circuit size (footprint or number of components) and complexity, without impacting other performance parameters, are disclosed. Phase shifter elements that can be disposed in both the active and passive bypass paths are also described. Moreover, devices using the same reconfigurable phase shifter elements in both active and bypass modes are described. Components of the phase shifters can also perform output matching when the phase shifters are implemented as part of an RF receiver front-end.

Abstract: Methods and devices addressing design of wideband LNAs with gain modes are disclosed. The disclosed teachings can be used to reconfigure RF receiver front-end to operate in various applications imposing stringent and conflicting requirements. Wideband and narrowband input and output matching with gain modes using a combination of the same hardware and a switching network are also disclosed. The described methods and devices also address carrier aggregation requirements and provide solutions that can be used both in single-mode and split-mode operations.
