Late in 2006 PSI released a Low Noise Divider Ensemble which provides low noise outputs at:

10.240 GHz

  5.120 GHz

  2.560 GHz  

  1.280 GHz

     640 MHz

     320 MHz

When the LNDE is driven by one of PSI's low phase noise sapphire oscillators these outputs can provide the lowest phase noise signals reported at these frequencies.
