MAX2608EUT+T

Overview

The MAX2608EUT+T is an integrated intermediate frequency voltage-controlled oscillator (VCO) operating within a frequency range of 300 MHz to 500 MHz. It features differential and single-ended outputs housed in a compact SOT-23-6 package. The device operates on a supply voltage between 2.7 V and 5.5 V, with a tuning voltage range of 400 mVDC to 6 VDC. Key electrical specifications include a typical output power of -10 dBm, a phase noise of -107 dBc/Hz, and a current consumption of 3.5 mA. It supports a push rate of 220 kHz/V and maintains secondary harmonics at -30 dBc.

Feature Summary

• Integrates varactor for tuning functionality
• Provides both differential and single-ended output configurations
• Utilizes small SOT-23-6 surface-mount packaging

Applications

• Cellular communication systems
• GPS receiver front ends
• ISM band transceivers

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the presence of the + suffix indicating lead-free RoHS compliance. Ensure the SOT-23-6 package matches design requirements. Check for recent manufacturing date codes to avoid potential obsolescence issues associated with legacy Maxim Integrated parts.

Selection Notes

Select this component when a low-power, small-footprint IF VCO is required for cellular or GPS applications. The dual-output capability simplifies circuit design by supporting both differential and single-ended architectures. Verify that the 300 MHz to 500 MHz frequency range aligns with the specific intermediate frequency requirements of the target system architecture.

Part Context

This part belongs to the MAX2607/MAX2608 family of integrated IF VCOs designed for wireless communications. Manufactured by Analog Devices under the Maxim Integrated brand, these components are optimized for mobile phone and PCS applications. The series focuses on providing high performance in minimal space, leveraging silicon germanium technology for improved radio front-end efficiency.

Replacement Considerations

The MAX2607EUT+T is a confirmed substitute within the same product family, offering similar integrated VCO functionality.
