ADF5002BCPZ

Overview

The ADF5002BCPZ is a divide-by-8 RF prescaler from Analog Devices, operating within a frequency range of 4 GHz to 18 GHz. Designed for low noise and low power consumption, it features an integrated RF decoupling capacitor structure and consumes 30 mA in active mode with a single 3.3 V supply. The device provides differential 100 Ω RF outputs suitable for direct interfacing with PLL ICs such as the ADF4156 or ADF4106. It exhibits a phase noise of −153 dBc/Hz at 12 GHz input and operates across an industrial temperature range of −40°C to +105°C.

Feature Summary

• Divide-by-8 prescaler function covering 4 GHz to 18 GHz input frequencies
• Low phase noise performance of −153 dBc/Hz at 12 GHz input offset by 100 kHz
• Integrated RF decoupling capacitors and differential 100 Ω outputs
• Single 3.3 V 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 specific ordering suffix when purchasing. The ADF5002BCPZ denotes the standard tube package, while the ADF5002BCPZ-RL7 variant indicates a tape and reel configuration. Both options share identical electrical specifications and temperature ranges. Confirm package compatibility with the target PCB footprint before procurement.

Selection Notes

Select this component for applications requiring division of high-frequency signals down to levels compatible with standard PLL inputs. Ensure the input signal sensitivity meets the minimum requirement of −10 dBm across the 4 GHz to 18 GHz band. The device requires a single 3.3 V supply and supports both single-ended and differential output configurations depending on system impedance requirements.

Part Context

The ADF5002BCPZ belongs to the ADF5002 series of RF prescalers manufactured by Analog Devices. It is specifically engineered to extend the operational frequency range of phase-locked loops. The part is housed in a 16-lead Lead Frame Chip Scale Package (LFCSP_WQ) measuring 3 mm × 3 mm, designed for compact surface-mount assembly.

Replacement Considerations

Public documentation confirms the ADF5002BCPZ-RL7 as a packaging variant of the same functional unit. No other cross-model substitutes are verified in the provided source material.
