MAX2620EUA+

Overview

The MAX2620EUA+ is a low-phase noise voltage-controlled oscillator (VCO) operating from 10 MHz to 1.05 GHz. It features a tuning voltage range of 500 mVDC to 3 VDC and delivers -8 dBm output power with a push rate of 71 kHz/V. The device operates on a single supply voltage between 2.7 V and 5.25 V, drawing 12.5 mA. It achieves -110 dBc/Hz phase noise at a 25 kHz offset and exhibits -29 dBc secondary harmonic distortion. Packaged in an 8-pin µMAX case measuring 3.05 mm x 3.05 mm x 0.95 mm, it functions within a temperature range of -40°C to +85°C.

Procurement Notes

Verify component authenticity through authorized Analog Devices channels. Confirm RoHS compliance status via official documentation. Ensure the supplier provides valid traceability records. Check for specific ordering suffixes that may affect packaging or temperature grade. Validate datasheet revisions against the manufacturing date code.

Selection Notes

Select this component when a compact VCO solution is required for frequencies up to 1.05 GHz. Consider the µMAX package constraints for PCB layout space. Evaluate the 12.5 mA current consumption against system power budgets. Verify that the 500 mV to 3 V tuning range aligns with available control voltages. Assess phase noise requirements relative to the -110 dBc/Hz specification at 25 kHz offset.

Part Context

The MAX2620 belongs to the Maxim Integrated RF oscillator family, designed for wireless communication applications. It replaces discrete oscillator solutions by integrating the resonator drive and buffering stages into a single surface-mount device. The series emphasizes low cost and small footprint while maintaining performance suitable for consumer and industrial radio systems.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure replacement parts match the 10 MHz to 1.05 GHz frequency range and µMAX-8 package dimensions. Verify compatibility with the 2.7 V to 5.25 V supply voltage and 12.5 mA current draw. Confirm equivalent phase noise and output power specifications.
