YigSynt 200

YigSynt 200 is a high performance synthesizer module which operates over the frequency range from 160 MHz to 20 GHz with the frequency resolution as fine as 0.001 Hz. The module is built around a fundamental 10-20 GHz YTO (YIG tuned oscillator) which yields no subharmonic products and excellent broadband phase noise (<-140 dBc/Hz at 1 MHz offset from 10 GHz). But an even more important advantage of the YigSynt is its excellent phase noise at close-in offsets across the entire frequency range. This synthesizer uses a top-class grade A 100 MHz OCXO in combination with a unique multi loop PLL technology which allows for achieving <-95/-124 dBc/Hz at 100 Hz/10 kHz offset from a 10 GHz carrier. The spurs are specified at <-70 dBc in the main frequency band (10-20 GHz) and drop 6 dB further down with each frequency division stage reaching a value of <-94 dBc in the 0.625-1.25 GHz frequency band. The YigSynt provides calibrated output power from -10 dBm to +10 dBm with less than +/-1 dB uncertainty and 0.5 dB adjustment step. Harmonics are lower than  -30 dBc at the maximum rated output power. The module is intended for use in various communications and test systems where the signal purity of the signal source is a primary concern. It is controlled via USB interface (the control software is included in the package). It comes in a robust aluminum milled case and operates over the frequency range of 0…+50°C. The module does need a heat sink.
