MAX2605EUT+T

Overview

The MAX2605EUT+T is an integrated intermediate frequency voltage-controlled oscillator (IF VCO) manufactured by Analog Devices Inc./Maxim Integrated. It operates within a frequency range of 45 MHz to 70 MHz and features differential outputs for improved signal integrity. The device functions on a supply voltage between 2.7 V and 5.5 V, drawing a typical current of 2.8 mA. It delivers an output power of -10 dBm with a secondary harmonic level of -30 dBc. The tuning voltage range spans from 400 mVDC to 6 VDC, providing a push sensitivity of 60 kHz/V. Phase noise is specified at -117 dBc/Hz. The component is housed in a compact SOT-23-6 surface-mount package.

Feature Summary

• Integrated IF VCO design with differential output configuration
• Low power consumption suitable for portable applications
• Compact SOT-23-6 surface-mount packaging

Applications

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

Procurement Notes

Verify availability status as the part may be subject to limited supply or special order requirements through distributors like Mouser. Confirm RoHS compliance details via official documentation before integration. Ensure the ordering suffix matches the required tape-and-reel or cut-tape format for your assembly process. Cross-reference the manufacturer part number with authorized channels to avoid counterfeit components.

Selection Notes

Select this component when a low-power, differential-output IF VCO is required for cellular, GPS, or ISM applications. The SOT-23-6 package suits space-constrained designs. Verify that the operating temperature range of -40°C to +85°C meets environmental requirements. Ensure the tuning voltage range aligns with the control circuitry capabilities.

Part Context

The MAX2605 belongs to the Maxim Integrated family of integrated IF VCOs designed for RF front-end modules. It replaces discrete oscillator solutions by combining the VCO core and necessary biasing into a single small-footprint package. This integration reduces board space and simplifies design complexity for wireless communication devices requiring stable intermediate frequency generation.

Replacement Considerations

Check for direct pin-compatible substitutes within the same product family. Verify if alternative VCOs offer wider frequency ranges or different output configurations if system requirements change. Consult the manufacturer's obsolescence notices for long-term supply assurance.
