The second generation of a compact frequency synthesizer from Wide Band Systems is well suited for measurement applications. The agile source tunes from 2 to 18 GHz in 1-MHz steps (other resolutions are available) with 3-microsecond typical switching speed. The output power across the full frequency range is +10 dBm and spurious outputs are -50 dBc or less. Phase noise is typically -90 dBc/Hz offset 1 kHz from a 10-GHz carrier, -107 dBc/Hz offset 100 kHz from a 10-GHz carrier and -121 dBc/Hz offset 1 MHz from the same carrier.
