Wideband receivers and methods of operation

A receiver comprising:

• a first set of one or more amplifier stages configured to amplify input signals in a plurality of communication bands;
• a second set of one or more amplifier stages selectively couplable to the first set of one or more amplifier stages, wherein the second set of one or more amplifier stages are configured to selectively receive the input signals in the plurality of communication bands amplified by the first set of one or more amplifier stages and to amplify one or more input signals in a first one of the plurality of communication bands;
• a first capacitor coupled between the first set of one or more amplifier stages and the second set of one or more amplifier stages;
• a first set of one or more mixers coupled to the second set of one or more amplifier stages, wherein the first set of one or more mixers are configured to receive the one or more input signals in the first communication band amplified by the second set of one or more amplifier stages, to receive one or more local oscillator signals for the first communication band, and to generate a baseband signal of the first communication band;
• a third set of one or more amplifier stages selectively couplable to the first set of one or more amplifier stages, wherein the third set of one or more amplifier stages are configured to selective receive the input signals in the plurality of communication bands amplified by the first set of one or more amplifier stages and to amplify one or more input signals in a second one of the plurality of communication bands;
• a second capacitor coupled between the first set of one or more amplifier stages and the third set of one or more amplifier stages;
• and
• a second set of one or more mixers coupled to the third set of one or more amplifier stages, wherein the second set of one or more mixers are configured to receive the one or more signals in the second communication band amplified by the third set of one or more amplifier stages, to receive one or more local oscillator signals for the second communication band, and to generate a baseband signal of the second communication band.
