MAX2624EUA-T

Overview

The MAX2624EUA-T is a monolithic voltage-controlled oscillator (VCO) from Analog Devices, operating within the 947 MHz to 998 MHz frequency range. It integrates an oscillator and output buffer in an 8-pin µMAX package. Key electrical specifications include a tuning voltage range of 400 mVDC to 2.4 VDC, a typical phase noise of -101 dBc/Hz at 10 kHz offset, and a drive capability of 280 kHz/V. The device consumes 11.5 mA of current, delivers -3 dBm output power, and exhibits a secondary harmonic level of -27 dBc.

Feature Summary

• Integrates oscillator core and output buffer into a single miniature component
• Provides wide tuning sensitivity for flexible frequency control applications
• Delivers low phase noise performance suitable for precision RF systems

Applications

• Wireless Local Loop (WLL) transceivers
• RF communication modules requiring stable local oscillation
• Frequency synthesis circuits in wireless infrastructure

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm RoHS compliance details as listed in official documentation. Validate lot codes and traceability records against current supply chain requirements. Ensure storage conditions meet specified environmental standards to maintain component integrity prior to assembly.

Selection Notes

Select this component when designing systems requiring a self-contained VCO solution within the 947-998 MHz band. Consider the integrated buffer output for simplified circuit topology compared to discrete oscillator designs. Evaluate the 11.5 mA current consumption against system power budgets. Assess the -101 dBc/Hz phase noise specification against system jitter tolerance requirements.

Part Context

This part belongs to the MAX262x series of self-contained voltage-controlled oscillators. These devices are designed to replace complex discrete LC tank circuits by providing a complete oscillation solution in a small footprint. The series targets applications needing reliable frequency generation without external resonant components, simplifying PCB layout and reducing design complexity for RF front-end modules.

Replacement Considerations

The MAX2624EUA-T is marked as obsolete and no longer manufactured. Engineers must identify qualified replacement parts that match the 947-998 MHz frequency range, 8-pin µMAX package, and similar electrical characteristics such as phase noise and current consumption.
