Profile: Phase Matrix, Inc. specializes in providing RF & microwave instruments, sub-systems, and components. QuickSyn™ microwave synthesizers employ a patented, revolutionary phase-refining technology that provides a unique combination of fast-switching speed and low phase-noise characteristics. Model FSW-0010 & FSW-0020 cover the frequency ranges of 0.5 to 10 GHz and 0.5 to 20 GHz respectively (extendable down to 0.1 GHz and 0.2 GHz). This synthesizers utilize a fundamental VCO to achieve the desired output frequency. In contrast to frequency multiplication schemes, this approach eliminates possible spectrum contamination from subharmonic products. The use of the advanced direct digital synthesis approach, enables a very fine frequency resolution of 0.001 Hz. The VCO noise is suppressed by utilizing an ultra low noise reference oscillator in conjunction with a low-noise locking mechanism. Microphonic effects are also greatly reduced due to the use of a low-mass VCO and very wide PLL filter bandwidth. Our microwave components and sub-assemblies include broadband, narrowband & fixed tuned VCOs, high speed clocks and phase locked oscillators.
