The FS020 ultra-low noise frequency doubler can be used with state-of-the-art crystal frequency sources without degrading phase noise or environmental stability. The  FS020 provides double the input frequency while  maintaining  spurious  modulation   less  than -50 dBc. The FS020 is ideal for phase lock applications, frequency synthesis chains and frequency distribution.  FS020 doublers are available at user specified input frequencies from 1 to 100 MHz.
