PLL frequency range extender Point-to-point radios VSAT radios Communications test equipment 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 RF outputs to allow direct interface to the differential RF inputs of PLLs such as the ADF4156 and ADF4106. Rev.
