The FS080 ultra-low noise frequency doubler can be used with state-of-the-art crystal frequency sources without degrading phase noise or environmental stability. The  FS080 provides  eight  times the  input  frequency while  maintaining  spurious  modulation   less  than -55 dBc. Optional outputs at X2, and X4 the input frequencies are available as an option.  The FS080  is ideal  for phase locking crystal sources  with 5 or 10 MHz  references.  The FS080  is available  in a stand-alone enclosure, NIM  module or aluminum enclosures.
