Abstract
An apparatus configured to separate from a received radio frequency (RF) signal a first low-frequency signal and a second low-frequency signal having different phases, up-convert the first low-frequency signal and the second low-frequency signal into a first intermediate frequency signal and a second intermediate frequency signal, respectively, and amplify the first and the second intermediate-frequency signals.
Claims21
An apparatus, comprising:
- a processor configured to separate from a received radio frequency signal a first low-frequency signal and a second low-frequency signal having different phases, to up-convert the first low-frequency signal and the second low-frequency signal into a first intermediate frequency signal and a second intermediate frequency signal, respectively, and to amplify the first and the second intermediate-frequency signals.
A method, comprising:
- separating, by a processor, from a received radio frequency signal a first low-frequency signal and a second low-frequency signal having different phases;
- up-converting, by the processor, the first low-frequency signal and the second low-frequency signal into a first intermediate frequency signal and a second intermediate frequency signal respectively;
- and
- amplifying, by the processor, the first and the second intermediate-frequency signals.
