ADF5001BCPZ-RL7

Overview

The ADF5001BCPZ-RL7 is a divide-by-4 RF prescaler from Analog Devices, operating within a frequency range of 4 GHz to 18 GHz. Designed for low phase noise applications, it achieves -150 dBc/Hz at 12 GHz with a 100 kHz offset. The device functions on a single 3.3 V supply, drawing 30 mA in active mode and 7 mA in power-down mode. It features integrated RF decoupling capacitors and differential 100 Ω outputs, allowing direct interfacing with PLLs like the ADF4156. Housed in a compact 3 mm × 3 mm LFCSP package, it supports industrial temperatures from -40°C to +105°C.

Feature Summary

• Divide-by-4 prescaler covering 4 GHz to 18 GHz input frequencies
• Low phase noise performance of -150 dBc/Hz at 12 GHz (100 kHz offset)
• Single 3.3 V supply operation with 30 mA active current consumption
• Integrated RF decoupling capacitors and differential 100 Ω outputs

Applications

• PLL frequency range extender
• Point-to-point radios
• VSAT radios
• Communications test equipment

Procurement Notes

Verify the component matches the specific Rev. A datasheet specifications before integration. Confirm that the LFCSP-16 package exposed paddle is properly grounded during assembly to ensure thermal and electrical performance. Check for moisture sensitivity handling requirements as indicated by the packaging type.

Selection Notes

Select this component when extending PLL frequency ranges above standard limits up to 18 GHz. Ensure the system design accommodates the 3.3 V supply voltage and provides adequate decoupling for the 30 mA active current draw. Consider the differential output interface compatibility with downstream PLL inputs such as the ADF4156 or ADF4106.

Part Context

This part belongs to the ADF5001 series of RF prescalers manufactured by Analog Devices. It is specifically designed to work in conjunction with integer-N PLL synthesizers to extend their operational frequency range into the microwave spectrum.

Replacement Considerations

The ADF5000BCPZ-RL7 serves as a functional alternative if a divide-by-2 prescaler is required instead of divide-by-4, maintaining similar package and supply characteristics.
