MAX2622EUA

Overview

The MAX2622EUA is a monolithic voltage-controlled oscillator (VCO) designed for the European ISM band, operating within a frequency range of 855 MHz to 881 MHz. It features a tuning voltage range of 400 mVDC to 2.4 VDC and delivers an output power of -3 dBm. The device operates on a supply voltage of 2.7 V to 5.5 V with a maximum current consumption of 11.5 mA. Key performance metrics include a phase noise of -101 dBc/Hz at 1 MHz offset, a pushing factor of 280 kHz/V, and a secondary harmonic level of -27 dBc. It incorporates an on-chip 50 Ohm output match and is housed in an 8-uMAX package.

Feature Summary

• Integrated 50 Ohm output matching network eliminates external components
• Monolithic design ensures stable operation across temperature variations
• Low current consumption suitable for battery-powered applications

Applications

• European ISM band transmitters
• Wireless sensor networks
• Short-range communication devices

Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS compliance requirements as the standard version may not meet current environmental standards. Check for alternative lead-free variants if regulatory compliance is mandatory for the target market. Ensure storage conditions adhere to manufacturer guidelines to prevent degradation of the surface-mount package.

Selection Notes

Select this component when designing for the specific 855-881 MHz European ISM frequency range. Consider the fixed output power and phase noise characteristics against system link budget requirements. Evaluate the 8-uMAX package dimensions for PCB layout constraints. Verify that the required tuning voltage range aligns with the available control circuitry in the design.

Part Context

The MAX2622 belongs to a family of monolithic VCOs optimized for ISM band applications. It offers a compact solution compared to discrete LC tank designs. The device integrates the oscillator core and matching network into a single small outline package, reducing board space and simplifying assembly processes for RF front-end modules.
