A novel sampling comparator circuit is presented for extending the pull-in range of microwave phase-locked oscillators (PLOs). It performs both phase and frequency detection without any frequency dividers, and a GaAs MMIC prototype is developed and tested. The proposed comparator improves the pull-in range by about 10 times more than is possible with conventional sampling phase detectors.
