The ADF5001 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 into a
PLL IC, such as the ADF4156 or ADF4106. The ADF5001
provides a divide-by-4 function. The ADF5001 operates off 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.
