Receiver RF front-end circuit and method of same

A method, comprising:

• receiving, by a low noise amplifier (LNA), a RF signal from an antenna;
• generating, by a frequency synthesizer and divider, a first local oscillation signal, a second local oscillation signal, a third local oscillation signal and a fourth local oscillation signal;
• outputting, by a first front-end circuit communicatively coupled to the low noise amplifier and the frequency synthesizer and divider, a first digital intermediate frequency signal and a second digital intermediate frequency signal, wherein the outputting the first digital intermediate frequency signal is implemented by
• mixing the amplified RF signal and the first local oscillation signal into a first intermediate frequency signal,
• filtering the first intermediate frequency signal, and
• converting the filtered first intermediate frequency signal into the first digital intermediate frequency signal, and
• wherein the outputting the second digital intermediate frequency signal is implemented by
• mixing the amplified RF signal, the first local oscillation signal and the second local oscillation signal into a second intermediate frequency signal,
• filtering the second intermediate frequency signal, and
• converting the filtered second intermediate frequency signal into the second digital intermediate frequency signal;
• and
• outputting, by a second front-end circuit communicatively coupled to the low noise amplifier and the frequency synthesizer and divider, a third digital intermediate frequency signal and a fourth digital intermediate frequency signal, wherein the outputting the third digital intermediate frequency signal is implemented by
• mixing the amplified RF signal and the third local oscillation signal into a third intermediate frequency signal,
• filtering the third intermediate frequency signal, and
• converting the filtered third intermediate frequency signal into the third digital intermediate frequency signal, and
• wherein the outputting the fourth digital intermediate frequency signal is implemented by
• mixing the amplified RF signal, the third local oscillation signal and the fourth local oscillation signal into a fourth intermediate frequency signal,
• filtering the fourth intermediate frequency signal, and
• converting the filtered fourth intermediate frequency signal into the fourth digital intermediate frequency signal.
