MAX2605EUT

Overview

The MAX2605EUT+T is an integrated intermediate frequency voltage-controlled oscillator (IF VCO) from Analog Devices, operating within a frequency range of 45 MHz to 650 MHz. It features differential outputs and operates on a supply voltage between 2.7 V and 5.5 V. The device draws a typical current of 7.5 mA and provides an output power of -10 dBm. Key electrical specifications include a tuning voltage range of 400 mVDC to 6 VDC, a push performance of 720 kHz/V, and a phase noise of -93 dBc/Hz. It is housed in a compact SOT-23-6 package with dimensions of 3 mm x 1.75 mm x 1.45 mm.

Feature Summary

• Integrated IF VCO design with differential output configuration for improved signal integrity
• Built-in bias control circuitry simplifies system integration and reduces external component count
• Wide frequency coverage spanning 45 MHz to 650 MHz suitable for multiple communication bands

Applications

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

Procurement Notes

Verify the exact suffix (+T vs -T) against your schematic requirements, as packaging or minor specification variations may exist. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement. Ensure availability checks are performed directly with authorized distributors, as stock levels fluctuate. Validate that the SOT-23-6 footprint matches your PCB layout constraints.

Selection Notes

Select this component when a low-power, integrated solution is required for IF stages in cellular or GPS receivers. The differential output capability makes it suitable for applications demanding high common-mode noise rejection. Consider the 2.7 V to 5.5 V supply range compatibility with your system's power architecture. The small SOT-23-6 package is ideal for space-constrained portable devices.
