MAX2620EUA+T

Overview

The MAX2620EUA+T is an integrated RF oscillator operating from 10MHz to 1050MHz. It features a tuning voltage range of 500mVDC to 3VDC and delivers -8dBm output power. Key electrical parameters include a push of 71kHz/V, secondary harmonic suppression of -29dBc, and phase noise of -110dBc/Hz. The device draws 12.5mA current and utilizes a TSSOP-8 (µMAX) package.

Feature Summary

• Integrates a low-noise voltage-controlled oscillator with two buffered outputs in a single component.
• Provides ultra-small surface-mount packaging for space-constrained designs.
• Offers wide frequency coverage suitable for various RF applications.

Applications

• Cellular communication systems
• Non-Public Cellular Systems (NPCS)
• Wireless Local Loop (WLL) transceivers

Procurement Notes

Verify component status carefully as the MAX2620EUA-T is listed as obsolete by Analog Devices. Confirm availability through authorized distributors or surplus channels. Ensure compatibility with RoHS requirements if specified, noting that some listings indicate non-RoHS variants. Validate datasheet revisions against current production batches to ensure performance consistency.

Selection Notes

Select this component for designs requiring a compact, low-cost VCO solution with integrated buffering. Consider the 10MHz to 1050MHz range and -110dBc/Hz phase noise profile. Evaluate the 500mV to 3V tuning voltage against available control circuitry. Account for the 12.5mA supply current in power budget calculations.

Part Context

Part of the MAX2620 series of RF oscillators. Designed for high-volume consumer and industrial RF markets. Shares functional similarities with other Maxim Integrated VCOs but distinguished by its specific frequency range and integrated buffer architecture.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Due to the obsolete status, alternative solutions may require redesigning the RF front-end or selecting a newer generation VCO with similar specifications from Analog Devices or competitors.
