1. A receiver comprising:
one or more wideband amplifier stages configured to amplify input signals in a plurality of communication bands;
one or more amplifier stages of a first band capacitively coupled to the one or more wideband amplifier stages, wherein the one or more amplifier stages of the first band are configured to amplify one or more input signals in a first one of the plurality of communication bands;
one or more mixers of the first band configured to generate one or more baseband signals from a frequency difference between the amplified input signals in the first one of the plurality of communication bands and one or more local oscillator signals for the first communication band;
one or more amplifier stages of a second band capacitively coupled to the one or more wideband amplifier stages, wherein the one or more amplifier stages of the second band are configured to amplify one or more input signals in a second one of the plurality of communication bands;
one or more mixers of the second band configured to generate one or more baseband signals from a frequency difference between the amplified input signals in the second one of the plurality of communication bands and one or more local oscillator signals for the second communication band; and
one or more baseband circuits configured to receive the one or more baseband signals;
wherein one or more amplifier stages of a given one of the plurality of communication bands and one or more of the mixers of the given one of the plurality of communication bands is selectively coupled between the one or more wideband amplifier stages and the one or more baseband circuits.
