What is an RF Frequency Synthesizer?

A frequency synthesizer is an electronic device that uses an oscillator to generate a signal with a specific frequency or within a pre-set frequency range. They utilize frequency multiplication, frequency division, direct digital synthesis, frequency mixing, and phase-locked loops to generate a stable output signal at a specific frequency with low phase noise.

There are three broad categories of frequency synthesizers:

  1. Direct Analog Synthesis
  2. Direct Digital Synthesis (DDS) 
  3. Indirect Digital (PLL) synthesizers including integer-N and fractional-N.

Frequency synthesizers can be found in various modern devices such as radio receivers, televisions, mobile telephones, radio telephones, walkie-talkies, CB radios, cable television converter boxes, satellite receivers, GPS systems, etc.

Important Parameters for a Frequency Synthesizer:

  • Output Frequency (MHz/GHz): It is the frequency or frequency range of the output signal generated by the synthesizer.
  • Phase Noise (dBc/Hz): For a carrier frequency at a given power level, the phase noise of a synthesizer is the ratio of the carrier power to the power found in a 1-Hz bandwidth at a defined frequency offset (usually 1 kHz for a synthesizer). Learn more about Phase Noise.
  • Reference Frequency: A high quality, low-phase-noise reference is also critical to a stable low-phase-noise RF output. The stability and accuracy of the frequency synthesizer's output are correlated to the stability and accuracy of its reference frequency input.
  • Output Power: It is the amplitude of the power of the output signal.
  • Spurious and Harmonics (dBc): Spurious and Harmonics are spikes of unwanted signals that are found at the output of a synthesizer. Any unwanted signal synthesized by the synthesizer outside the pre-programmed frequency band can be termed Spurious signal. Harmonics are a subset of Spurious signals found at integer multiples of the fundamental frequency of the signal. Learn more.
