ABSTRACT:
A ratiometric transmit path architecture for communication systems and related methods are disclosed. This ratiometric transmit path architecture utilizes a single local oscillator signal and dividers to provide mixing signals for intermediate frequency (IF) mixing circuitry and feedback mixing circuitry, thereby eliminating the need for separate IF and radio frequency (RF) voltage controlled oscillators (VCOs) in prior solutions.
