Abstract
Methods and devices to implement efficiently an AUX terminal in RF front end receivers using LNAs are described. The described methods implement a smaller number of switches resulting in an overall performance improvement by reducing the noise figure at the input of the LNA. The presented devices can be used in low/high gain and bypass modes and can accommodate an arbitrary number of bands over a wide frequency range.
