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.
