INTEGROUS SIGNAL COMBINER
First Claim
1. An integrous signal combiner comprising:
- a plurality of inputs, each input configured to receive a signal of a different frequency than the other inputs of the plurality of inputs;
an output configured to provide an integrous signal to a subsequent processing block;
a plurality of low noise amplifiers (LNAs); and
a plurality of resonant circuits, each resonant circuit corresponding to a different LNA from the plurality of LNAs.

Abstract
A front-end module (FEM) is disclosed that includes an integrous signal combiner. The integrous signal combiner can process received signals and use a set of resonant circuits to filter signal noise prior to recombination of a plurality of signal bands that form an aggregate carrier signal. These resonant circuits may be placed after a set of low noise amplifiers and can be used to more efficiently reduce noise and parasitic loading within each of a set of signal paths. Each resonant circuit may be configured to filter noise relating to a bandwidth for a signal that is to be combined with the signal of the signal path that includes the resonant circuit. In some implementations, the integrous signal combiner can be a tunable integrous signal combiner with resonant circuits that may be reconfigurable or dynamically configurable.
