MAX2750EUA+

Overview

The MAX2750EUA+ is a monolithic voltage-controlled oscillator (VCO) designed for the 2.4 GHz to 2.5 GHz ISM band. It integrates a fully functional oscillator and output buffer within an 8-pin µMAX package. The device operates with a tuning voltage range of 400 mVDC to 2.4 VDC, delivering -3 dBm output power. Key electrical specifications include a phase noise of -235 dBc/Hz, a secondary harmonic level of -30 dBc, and a current consumption of 21 mA.

Feature Summary

• Integrates a complete oscillator circuit and output buffer in a single chip
• Utilizes SiGe technology to replace traditional discrete modules
• Features an internally matched output buffer for direct interfacing

Applications

• Wireless LAN transceivers
• Bluetooth module designs
• ISM band communication systems

Procurement Notes

Verify component authenticity through authorized Analog Devices channels. Confirm RoHS compliance status prior to integration. Review the official datasheet for handling precautions related to electrostatic discharge sensitivity. Ensure supply chain stability as availability may be subject to manufacturer allocation or discontinuation notices.

Selection Notes

Select this component for applications requiring a compact solution for 2.4 GHz frequency generation. Evaluate the specific phase noise requirements against the -235 dBc/Hz specification. Consider the 21 mA current draw for battery-powered system efficiency. Verify that the 8-pin µMAX package fits the target PCB layout constraints.
