Abstract:
A receiver can include a first set of one or more amplifier stages configured to amplify input signals in a plurality of communication bands. The receiver can further include a second and third set of one or more amplifier stages. The second set of one or more amplifier stages can be 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. Alternatively, the third set of one or more amplifier stages can be 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 second one of the plurality of communication bands. A first set of one or more mixers can be configured to receive the 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 from a frequency difference of the signal of the first communication band and the one or more local oscillator signals for the first communication band. A second set of one or more mixers can be configured to receive the input signal 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.
