ADF5901ACPZ

Overview

The ADF5901ACPZ is a 24 GHz transmit monolithic microwave integrated circuit (MMIC) designed for radar systems. It integrates a 24 GHz voltage-controlled oscillator (VCO) with a programmable gain amplifier (PGA) and features two transmit channels with power amplifier outputs. The device operates within the ISM band, specifically covering frequencies from 24 GHz to 24.25 GHz. It is housed in a compact 32-lead Lead Frame Chip Scale Package (LFCSP) measuring 5 mm by 5 mm. The component supports an operating temperature range from -40°C to +105°C and utilizes silicon technology.

Feature Summary

• Integrates a 24 GHz VCO with PGA and dual transmit channels for radar applications
• Compact 32-lead LFCSP package design suitable for space-constrained systems
• Supports wide industrial operating temperature range from -40°C to +105°C

Applications

• 24 GHz FMCW radar systems
• ISM band radar transmitters
• Automotive sensing applications

Procurement Notes

Verify the specific suffix of the ordered part number against the official Analog Devices datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the LFCSP-32 footprint matches your PCB layout requirements. Check current supply status as availability may be restricted or subject to allocation. Ensure thermal management solutions are adequate for the specified operating temperature range during system integration.

Selection Notes

Select this component when a fully integrated 24 GHz transmitter solution is required for radar designs. It eliminates the need for external oscillators and amplifiers by combining VCO, PGA, and PA functions. Consider the LFCSP-32 package size for board space limitations. Verify compatibility with the target ISM band frequency regulations. Evaluate thermal performance needs given the high-frequency operation and integrated power stages.

Part Context

The ADF5901ACPZ belongs to the ADF5901 series of RF transmitters from Analog Devices. It is part of a family of MMICs designed for 24 GHz radar applications. The device serves as a core transmission component, providing signal generation and amplification. It is distinct from receiver-focused MMICs and complements other radar subsystem components like mixers and detectors.
