Abstract: An apparatus, including: a first antenna port; a first set of one or more band filters coupled to the first antenna port; a first set of one or more low noise amplifiers (LNAs) coupled to the first set of one or more band filters, respectively; a second antenna port; a second band filter; a second low noise amplifier (LNA); a first switching device coupled between the second antenna port and the second LNA; and a second switching device coupled between the second antenna port and the second band filter.

Abstract: Devices and techniques for amplifying a signal are disclosed. For instance, an amplifier includes an input node and an output node; a first gain segment including: a first transistor, where a gate of the first transistor is coupled to the input node, a first terminal of the first transistor is coupled to a ground, and a second terminal of the first transistor is coupled to the output node; a second gain segment including: a second transistor, where a gate of the second transistor is coupled to the input node, a first terminal of the second transistor is coupled to the ground, and a second terminal of the second transistor is coupled to the output node, where the first gain segment and the second gain segment are arranged in parallel with respect to the output node; and a bias circuit.
