摘要： An improved method of cycle slip prevention in a frequency synthesizer is achieved by determining phase error between a divided VCO and reference, determining whether a phase error of a full cycle slip has occurred and in which direction and altering the phase of the VCO divided signal in the amount and direction to reduce the phase error to less than one reference cycle. The result is an improved transfer function of the PFD, proportional to the phase error in the region -2*pi to 2*pi, and fixed close to maximum when the phase error exceeds the above interval. This invention is achieved with the addition of digital circuitry to monitor and control the PFD and the VCO divider, and does not require additional analog charge pump circuitry.

摘要： An RF detector configured to provide two outputs, one being a function of the true RMS power level of an RF input signal, and the other being a function of the instantaneous/peak power of the RF input signal, normalized to the average power level. The RF detector includes a variable gain detection subsystem including a single detector or detector array that provides a representation of the power level of the RF input signal. The detector or detector array is common to both the RMS power detection channel and the instantaneous/peak power detection channel of the RF detector. A method of RF detection includes providing representations of the RF input signal at different gain levels, selecting one or more of the representations, and averaging the selected signals. The gain levels of the selected representations is adjusted to provide information about the average power level of the RF input signal.

摘要： A fast turn on compensation system for a synthesized signal source includes a synthesized signal source coupled to a power supply and configured to generate a phase stable radio frequency (RF) output signal. A mute amplifier is coupled to the synthesized signal source and the power supply. A dummy amplifier is coupled to the mute amplifier and the power supply. A mute controller is coupled to the mute amplifier and the dummy amplifier, the mute controller is responsive to an enable signal and configured to enable the dummy amplifier and disable the mute amplifier when no RF output signal is being generated and disable the dummy amplifier and enable the mute amplifier when the RF output signal is being generated such that total power supply current delivered to the synthesized signal source and the dummy amplifier or mute amplifier is approximately constant before, during, and after enabling the mute amplifier to reduce phase disturbance of the RF output signals.
