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 ADF4156 or the ADF4106. The ADF5000

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.
