Abstract
A receiver topology for supporting various combinations of interband carrier aggregation (CA) signals, intraband non-contiguous CA and non-CA signals having different combinations of signals aggregated therein.
Claims28
A low noise amplifier (LNA) circuit including:
- (a) a first LNA having an input configured to receive a first input signal and configured to selectively provide an amplified first output signal to a first circuit output;
- (b) a second LNA having an input configured to receive a second input signal and configured to selectively provide an amplified second output signal to a second circuit output;
- and
- (c) a split LNA having an input configured to receive a third input signal and configured to selectively provide an amplified third output signal to the first circuit output and/or an amplified fourth output signal to the second circuit output.

A low noise amplifier (LNA) circuit including:
- (a) a first LNA having an input configured to receive a first input signal and configured to selectively provide an amplified first output signal on a first circuit output;
- (b) a second LNA having an input configured to receive a second input signal and configured to selectively provide an amplified second output signal on a second circuit output;
- and
- (c) a split LNA comprising a first cascode amplifier stage and a second cascode amplifier stage, each cascode amplifier stage having an input configured to receive a third input signal, the first cascode amplifier stage configured to selectively provide an amplified third output signal from an output of the first cascode amplifier stage to the first circuit output and the second cascode amplifier stage configured to selectively provide an amplified fourth output signal from an output of the second cascode amplifier stage to the second circuit output.
