MAX2624EUA+

Overview

The MAX2624EUA+ is a monolithic voltage-controlled oscillator (VCO) from Analog Devices, housed in an 8-pin uMAX package. It operates within a frequency range of 10 MHz to 1.05 GHz, powered by a supply voltage between 2.7 V and 5.25 V. The device delivers -8 dBm output power with a tuning voltage range of 500 mVDC to 3 VDC. Key electrical specifications include a phase noise of -110 dBc/Hz, a secondary harmonic level of -29 dBc, and a drive capability of 71 kHz/V. It draws 12.5 mA current and functions reliably across temperatures from -40°C to +85°C.

Feature Summary

• Integrates LC oscillator topology into a compact monolithic design
• Provides wide frequency coverage from 10 MHz to 1.05 GHz
• Supports low-voltage operation for portable applications

Applications

• Wireless communication systems
• RF signal generation circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lot traceability prior to acquisition. Ensure storage conditions meet specified humidity and temperature limits to maintain integrity. Review datasheet revisions for any functional updates. Validate pinout compatibility with existing PCB layouts before finalizing orders.

Selection Notes

Evaluate the required frequency span against the 10 MHz to 1.05 GHz operational range. Assess power consumption requirements relative to the 12.5 mA current rating. Consider thermal management needs given the -40°C to +85°C operating window. Verify that the uMAX-8 package dimensions fit the target board space. Compare phase noise performance against system sensitivity thresholds.
