Abstract

A system comprises a microwave backhaul outdoor unit having a first resonant circuit, phase error determination circuitry, and phase error compensation circuitry. The first resonant circuit is operable to generate a first signal characterized by a first amount of phase noise and a first amount of temperature stability. The phase error determination circuitry is operable to generate a phase error signal indicative of phase error between the first signal and a second signal, wherein the second signal is characterized by a second amount of phase noise that is greater than the first amount of phase noise, and the second signal is characterized by a second amount of temperature instability that is less than the first amount of temperature instability. The phase error compensation circuitry is operable to adjust the phase of a data signal based on the phase error signal, the adjustment resulting in a phase compensated signal.

Claims (5)

1 . A system comprising:

a microwave backhaul outdoor unit comprising:

a first resonant circuit operable to generate a first signal characterized by a first amount of phase noise and a first amount of temperature stability;

phase error determination circuitry operable to generate a phase error signal indicative of phase error between said first signal and a second signal, wherein said second signal is characterized by a second amount of phase noise that is greater than said first amount of phase noise, and said second signal is characterized by a second amount of temperature instability that is less than said first amount of temperature instability;

phase error compensation circuitry operable to adjust the phase of a data signal based on said phase error signal, said adjustment resulting in a phase compensated signal.
