ADF5002BCPZ-RL7

Overview

The ADF5002BCPZ-RL7 is a divide-by-8 RF prescaler from Analog Devices, operating within a frequency range of 4 GHz to 18 GHz. It features low phase noise of −153 dBc/Hz at 12 GHz with a 100 kHz offset and consumes 30 mA in active mode from a single 3.3 V supply. The device provides differential 100 Ω RF outputs for direct interface with PLLs like the ADF4156. Packaged in a 16-lead LFCSP (3 mm × 3 mm), it supports an industrial temperature range of −40°C to +105°C.

Feature Summary

• Divide-by-8 fixed RF divider function covering 4 GHz to 18 GHz input frequencies
• Low phase noise performance of −153 dBc/Hz at 12 GHz input with 100 kHz offset
• Differential 100 Ω RF outputs with integrated decoupling capacitors for direct PLL interfacing
• Single 3.3 V power supply operation with 30 mA active current consumption

Applications

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

Procurement Notes

Verify the ordering suffix RL7 indicates 7-inch tape and reel packaging. Confirm the B version designation corresponds to the industrial temperature range of −40°C to +105°C. Ensure compliance with RoHS standards as indicated by the Z suffix in the base part number. Check for moisture sensitivity requirements during storage and handling.

Selection Notes

Select this component when extending the frequency range of integer-N synthesizers above their native limits. Ensure the downstream PLL accepts differential inputs or design appropriate single-ended conversion. Verify that the input signal level falls within the specified sensitivity range of −10 dBm to +10 dBm for optimal harmonic performance.

Part Context

This prescaler belongs to the ADF5002 series designed to complement Analog Devices' ADF4xxx PLL family. It serves as a front-end divider block, allowing lower-frequency PLLs to synthesize signals up to 18 GHz. The device integrates internal biasing and decoupling to simplify PCB layout compared to discrete solutions.
