MAX2620EUA-T

Overview

The MAX2620EUA-T is an integrated RF voltage-controlled oscillator (VCO) manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a frequency range of 10 MHz to 1050 MHz and utilizes a single power supply ranging from +2.7 V to +5.25 V. The device features two buffered outputs for load isolation and exhibits low phase noise, reaching -110 dBc/Hz at a 25 kHz offset. Key electrical parameters include a tuning voltage range of 500 mVDC to 3 VDC, a typical push of 71 kHz/V, and a current consumption of 12.5 mA. The output power is specified at -8 dBm with a secondary harmonic level of -29 dBc.

Feature Summary

• Integrated silicon bipolar design offering low phase noise performance
• Dual buffered outputs providing inherent load isolation
• Insensitive to power supply variations for stable operation
• Wide frequency coverage from 10 MHz to 1050 MHz

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'T' indicates reel packaging if required for automated assembly. Check RoHS compliance status as indicated in official documentation. Ensure the part number matches the exact request to avoid confusion with non-tape versions. Validate datasheet revisions against the latest public release.

Selection Notes

Select this component when a wide tuning range and low phase noise are critical for RF front-end designs. Consider the 8-µMAX package constraints for PCB layout. Evaluate the -8 dBm output power against subsequent amplifier requirements. Verify that the 12.5 mA current draw fits within the system's power budget. Ensure the 500 mVDC to 3 VDC tuning voltage range aligns with available control circuitry.

Part Context

The MAX2620 belongs to a family of integrated RF oscillators designed for cost-effective wireless applications. It replaces discrete LC tank circuits with a monolithic solution, simplifying design complexity. The µMAX package allows for compact surface-mount implementation. This series supports various cellular and wireless standards requiring stable frequency generation.
