ADF5901WCCPZ

Overview

The ADF5901WCCPZ is a 24 GHz monolithic microwave integrated circuit (MMIC) transmitter designed for radar systems. It integrates a voltage-controlled oscillator (VCO), a programmable gain amplifier (PGA), and dual transmit channels with power amplifier outputs. The device operates within the 24 GHz ISM band, utilizing a 32-lead LFCSP package. Key electrical parameters include a supply voltage range of 3.13 V to 3.465 V and an operating temperature range from -40 °C to +105 °C. The component features a gain of 22 dB and is RoHS compliant.

Feature Summary

• Integrates a 24 GHz VCO with PGA and dual Tx channels for radar applications
• Provides on-chip power amplifier outputs for direct transmission
• Operates in the 24 GHz ISM frequency band
• Available in a compact 32-lead LFCSP surface-mount package

Applications

• Automotive radar systems
• Short-range sensing applications
• Industrial monitoring sensors
• Security and access control systems

Procurement Notes

Verify the specific suffix 'W' against the official Analog Devices datasheet to confirm the exact variant specifications, as ordering suffixes may denote package type or temperature grade variations. Ensure compatibility with the target PCB footprint for the LFCSP-32 package. Cross-reference the AEC-Q100 qualification status if automotive reliability is required for the final design implementation.

Selection Notes

Select this component when a highly integrated 24 GHz solution is required to minimize external passive components. The inclusion of both VCO and PGA reduces board space compared to discrete solutions. Consider the dual-channel architecture if simultaneous or switched radar operations are needed. Verify that the 3.13 V to 3.465 V supply range aligns with the system's power management strategy.

Part Context

The ADF5901 belongs to Analog Devices' family of 24 GHz MMIC transmitters. It serves as a complete transmitter front-end, distinguishing itself from receivers or transceivers by focusing solely on signal generation and amplification. Related models in the series, such as the ADF5902, offer multi-channel FMCW capabilities, while the ADF5901 specifically targets dual-channel PA output requirements for simpler radar architectures.
