Abstract:
1. An RF transmitter, comprising: digital processor including a digital signal generation block for producing outgoing digital IF signals comprising an envelope magnitude component and a phase component wherein the envelope magnitude component is produced onto an envelope signal path and wherein the phase component is produced on a phase signal path; wherein the digital processor further includes: time shift signal determination logic that produces a time shift signal based upon a bleed over power level in an adjacent channel, which bleed over power level is a function of downstream phase and magnitude mismatch of a primary signal; and a time shift block operably coupled to receive one of the envelope magnitude component and the phase component from the digital signal generation block, wherein the time shift block generates a time shift in at least one of the envelope signal path and the phase signal path based upon the time shift signal, the time shift block further including:
