Method and system for rf front-end calibration scheme using fractional-n frequency synthesized signals and rssi

A system for processing signals in a wireless device, the system comprising:

• a multi-band wireless receiver chip comprising an on-chip frequency synthesizer;
• said frequency synthesizer is operable to generate a signal;
• and
• said multi-band wireless receiver is operable to dynamically modify a gain in a low-noise amplifier (LNA) within said multi-band wireless receiver chip for a receiver channel, by applying a control signal based on said generated signal to at least one tunable load communicatively coupled to said LNA.

A method for wireless communication, the method comprising:

• adding a received signal with a reference oscillator signal to generate an added signal;
• generating a mixed signal from said added signal using said reference oscillator signal;
• and
• tuning a wireless antenna that receives said received signal based on a received signal strength indicator (RSSI) associated with said mixed signal.

A system for wireless communication, the system comprising:

• at least one circuit, within a receiver comprising a receive wireless antenna, that enables adding of a received signal with a reference oscillator signal to generate an added signal;
• said at least one circuit enables generation of a mixed signal from said added signal using said reference oscillator signal;
• and
• said at least one circuit enables tuning of said receive wireless antenna based on a received signal strength indicator (RSSI) associated with said mixed signal.
