ADF5002BCPZ - 4-18 GHz Divide-by-8 RF Prescaler | Analog Devices
MPN： ADF5002BCPZ ✓ 啟用中ADF5002BCPZ 概覽
An RF prescaler is a frequency divider block used in radio-frequency signal chains. It belongs to the broader clock-and-timing IC hierarchy, where a prescaler can be used ahead of a phase-locked loop to divide down microwave or millimeter-wave signals. The ADF5002 provides a fixed divide-by-8 function for applications requiring predictable division ratio and direct connection to compatible PLL frequency synthesizers.
The ADF5002 is positioned as a low-noise, low-power RF divider block. Its specified operating frequency range extends to 18 GHz, while the 3.3 V supply supports integration into RF and microwave systems requiring a divided reference or feedback signal. Differential 100 ohm RF outputs are intended for direct interfacing with RF circuitry when the board-level impedance and termination requirements are satisfied.
The fixed divide-by-8 architecture makes this part most useful when the system frequency plan can accommodate an eightfold reduction. Using the prescaler before a PLL can lower the frequency presented to the synthesizer while preserving the relationship between the RF signal and the generated reference. Signal integrity, grounding, supply decoupling, and output matching remain important because RF divider performance is influenced by the complete transmission-line environment.
Typical applications include microwave and millimeter-wave downconversion, RF instrumentation, synthetic-frequency generation, test equipment, and communications equipment using a compatible PLL such as the ADF4156 or ADF4106. The divider can also support frequency-counter and measurement architectures where a high-frequency signal must be reduced before further processing.
When designing around the ADF5002BCPZ, preserve the manufacturer-recommended RF trace geometry and provide a low-impedance return path for the differential outputs. Verify the complete frequency plan before selecting the device: the input must fall within the 4 GHz to 18 GHz operating range, and the divided output must remain suitable for the downstream PLL or counter. Use the manufacturer datasheet and its recommended application circuit when defining impedance, bypass capacitance, and exposed-pad thermal connections.

典型應用
ADF5002BCPZ 適用於 6 應用s: Microwave PLL Frequency Divider, RF Test and Measurement Equipment, Wireless Transceiver Frequency Synthesis, Microwave Frequency Counter Front End, Synthetic Frequency Generator, RF Communications Signal Conditioning.
Microwave PLL Frequency Divider
The ADF5002BCPZ fits a microwave PLL frequency-divider stage where an RF signal in the 4 GHz to 18 GHz range must be reduced before entering a PLL. Its fixed divide-by-8 ratio lowers the frequency presented to the downstream synthesizer while retaining a defined relationship to the source signal. The 3.3 V supply integrates well with low-voltage RF systems, and the differential 100 ohm outputs support a controlled RF interface when the board layout follows the manufacturer application guidance. A compatible PLL such as the ADF4156 or ADF4106 can then receive the divided signal, subject to matching and frequency-plan verification.
推薦
RF Test and Measurement Equipment
The ADF5002BCPZ can divide a high-frequency test signal for use in RF counters, signal analyzers, and other measurement instruments. A 4 GHz to 18 GHz input divided by eight produces a lower-frequency signal that can simplify the architecture of a subsequent measurement or synthesizer stage. The low-noise, low-power divider architecture is useful when the instrument must preserve signal integrity during frequency conversion. Differential 100 ohm RF outputs should be routed with controlled impedance and tested for adequate isolation, return loss, and amplitude balance across the intended operating band.
推薦
Wireless Transceiver Frequency Synthesis
The ADF5002BCPZ is suitable for the divider portion of a wireless transceiver frequency-synthesis chain. The part accepts an RF signal from 4 GHz to 18 GHz and applies a fixed divide-by-8 operation before the signal reaches a PLL. This arrangement can reduce the frequency that must be handled by the PLL while maintaining a predictable relationship to the radio reference. The 3.3 V operating supply supports compact RF designs, while the differential 100 ohm output interface helps provide a controlled connection to the next RF stage.
推薦
Microwave Frequency Counter Front End
The ADF5002BCPZ can serve as the RF prescaler in a microwave frequency-counter front end. Dividing a 4 GHz to 18 GHz input by eight creates a lower-frequency signal for counting or comparison circuitry, reducing the frequency burden on the downstream stage. The fixed division ratio is useful for a planned frequency architecture because the relationship between input and output remains deterministic. Practical implementation still requires careful RF layout, controlled differential routing, and verification that the divided signal amplitude and frequency meet the counter or time-base requirements.
推薦
Synthetic Frequency Generator
The ADF5002BCPZ can be integrated into a synthetic-frequency generator when a high-frequency reference or feedback path must be divided by eight. The resulting lower-frequency signal can feed a PLL that generates the required output frequency, while the fixed divider simplifies the ratio planning. Since the part operates from 3.3 V and uses differential 100 ohm RF outputs, it is appropriate for compact microwave instrument architectures. The output network and the exposed pad should be designed according to the manufacturer recommendations, particularly when long RF routes or temperature changes could affect matching.
推薦
RF Communications Signal Conditioning
The ADF5002BCPZ can condition an RF communications signal before PLL-based frequency conversion. Its divide-by-8 function is appropriate when a 4 GHz to 18 GHz carrier or feedback signal must be converted to a lower frequency for processing. The differential output arrangement provides a defined interface for controlled RF routing, and the 3.3 V supply supports integration with compact communication electronics. Designers should confirm the required output level, isolation, impedance, and allowed operating bandwidth against the complete system budget before finalizing the signal path.

主要差異化特點
- Directly identified replacement configuration (對比ADF5002BCPZ-RL7)

- Differential RF output for controlled signal-chain integration (對比ADF41020BCPZ-RL7)
設計說明
Route the differential RF outputs as a controlled-impedance pair and keep the route as short as practical. Provide a continuous ground reference beneath the RF traces and follow the manufacturer application layout for the 16-WFQFN exposed-pad package. Confirm the intended output termination and downstream interface before fixing the trace geometry.
Decouple the 3.3 V supply close to the device and preserve a low-impedance return path from the supply and ground pins. RF prescaler performance can be influenced by supply noise and unstable reference conditions. Use the manufacturer recommended capacitor arrangement and check the decoupling network against the intended operating bandwidth.
Connect the exposed pad to the PCB ground plane using the manufacturer land pattern and adequate thermal-via arrangement. Although the device is described as low power, the exposed pad provides the primary thermal path from the die. Good copper connectivity and via placement help maintain consistent RF performance and device temperature across the operating environment.
Do not treat any same-family Analog Devices device as automatically interchangeable. The ADF5000BCPZ and ADF41020BCPZ-RL7 were identified in comparison material, but their divider ratios, frequency limits, and functions can differ from the ADF5002. Check the pin description, input range, output interface, and application circuit for the exact replacement MPN.
