GENERAL DESCRIPTION
The ADF5000 prescaler is a low noise, low power, fixed RF
divider block that can be used to divide down frequencies as
high as 18 GHz to a lower frequency suitable for input to a
PLL IC, such as the
provides a divide-by-2 function. The ADF5000 operates from
a 3.3 V supply and has differential 100 Ω RF outputs to allow
direct interface to the differential RF inputs of PLLs such as
the ADF4156 and ADF4106.
