MAX2609EUT+T

Overview

The MAX2609EUT+T is an integrated intermediate frequency voltage controlled oscillator (VCO) manufactured by Analog Devices Inc./Maxim Integrated. It operates within a frequency range of 500 MHz to 650 MHz and is housed in a SOT-23-6 package. The device supports a supply voltage between 2.7 V and 5.5 V, with a typical current consumption of 7.5 mA. It features differential output capability, delivering -10 dBm power with -30 dBc second harmonic suppression. The tuning voltage range spans from 400 mVDC to 6 VDC, providing a push of 720 kHz/V. Phase noise is specified at -93 dBc/Hz. The component functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrated intermediate frequency voltage controlled oscillator design
• Differential and single-ended output configuration
• Compact SOT-23-6 surface-mount packaging

Applications

• Cellular communication systems
• GPS receiver modules
• ISM band transceivers

Procurement Notes

Verify the specific suffix (+T) against the manufacturer's latest datasheet to ensure compatibility with required tape-and-reel specifications. Confirm that the SOT-23-6 footprint matches the target PCB layout dimensions. Check for RoHS compliance documentation as indicated in official product attributes. Ensure the supply voltage range aligns with the system's power delivery network capabilities before integration.

Selection Notes

Select this component when a compact, low-power VCO is required for IF applications in the 500-650 MHz range. The differential output option reduces common-mode noise compared to single-ended variants. Consider the 7.5 mA current draw for battery-operated devices. Verify that the tuning voltage range fits within the available control circuitry limits. The wide operating temperature range suits industrial or automotive environments.

Part Context

The MAX2609 belongs to Maxim Integrated's family of integrated IF VCOs designed for RF front-end applications. It replaces discrete oscillator solutions by combining the tank circuit and amplifier in a small form factor. This integration simplifies board layout and reduces component count. The device is optimized for cost-sensitive consumer electronics while maintaining performance standards for wireless communications.
