ADF41020BCPZ

Overview

The ADF41020BCPZ-RL7 is an 18 GHz microwave PLL synthesizer manufactured by Analog Devices Inc. It operates within a frequency range of 4 GHz to 18 GHz and supports integer-N synthesis architectures. The device features a low-noise digital phase frequency detector, a precision charge pump with programmable currents up to 5.0 mA, and a programmable reference divider. Key electrical parameters include a typical supply current of 30 mA at 3.0 V and an operating temperature range from -40°C to +85°C. It utilizes a 20-pin LFCSP package and includes a software-compatible interface with the ADF4106/ADF4107/ADF4108 family.

• Semiconductor test equipment
• Radar applications

Procurement Notes

Verify component status as the ADF41020BCPZ-RL7 is listed as End-of-Life (EOL) in public distributor records. Confirm availability through authorized channels or secondary markets. Ensure compliance with RoHS directives and check for specific environmental certifications required for the intended deployment environment before finalizing procurement decisions.

Selection Notes

Select this component when designing local oscillators for up-conversion or down-conversion sections requiring frequencies up to 18 GHz. It is suitable for systems aiming to eliminate frequency doubler stages due to its high bandwidth capabilities. Ensure the external Voltage Controlled Oscillator (VCO) and loop filter are designed to match the device's 2.85 V to 3.15 V supply requirements and charge pump characteristics.

Part Context

This part belongs to the ADF41020 series of microwave PLL synthesizers from Analog Devices. It shares pinout compatibility with the ADF4106, ADF4107, and ADF4108 families, allowing for minor layout changes during design updates. The device is designed to simplify system architecture by enabling direct drive of external microwave VCOs without intermediate multiplication stages.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, alternative solutions may require redesigning the PCB layout if pinouts differ from the legacy ADF4106/ADF4107/ADF4108 family members.
