The ADF5001 is a low noise, low power, fixed RF divider that can divide 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 and operates off a 3.3 V supply with differential 100Ω RF outputs.
The ADF5001 prescaler provides a fixed divide‑by‑4 function for frequencies up to 18 GHz, featuring low phase noise (‑150 dBc/Hz), low power consumption (30 mA active, 7 mA power‑down), and a single 3.3 V supply. It includes integrated RF decoupling capacitors and differential 100 Ω RF outputs for direct connection to compatible PLLs such as the ADF4156 or ADF4106.
The device is supplied in a 3 mm × 3 mm LFCSP package with an exposed paddle that must be grounded. Pin functions include RF input, differential RF outputs, chip enable, and separate supply pins for the input and output stages. An evaluation board with SMA connectors and a detailed bill of materials is provided for testing and integration.
