Abstract
A signal source with a wireless frequency reference. A signal loop includes an amplifier and a coupler. The magnitude of the loop gain in the signal loop is substantially equal to 1 at a steady-state amplitude of a signal at a fundamental frequency. A reference oscillator is coupled to the loop through the coupler, via a wireless link, and provides phase stabilization. The loop may include a nonlinear transmission line, to generate a comb output spectrum.
