MAX2622EUA-T

Overview

The MAX2622EUA-T is a monolithic voltage-controlled oscillator (VCO) from Analog Devices, designed for the European ISM band. It operates within a frequency range of 855 MHz to 881 MHz with a center frequency of 868 MHz. The device features an integrated output buffer and on-chip 50 Ohm matching network. Key electrical specifications include a tuning voltage range of 0.4 VDC to 2.4 VDC, a typical push of 280 kHz/V, and a tuning sensitivity of 75 MHz/V. Output power is rated at -3 dBm with secondary harmonics at -27 dBc. Phase noise is typically -101 dBc/Hz. The component draws 11.5 mA current and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates oscillator and output buffer in a miniature 8-pin package
• Includes on-chip 50 Ohm output matching network
• Optimized for European ISM band applications

Applications

• European ISM band communication systems
• Wireless sensor networks
• Industrial monitoring equipment

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as historical data may vary by production batch. Ensure the supplier provides official documentation to validate the part number against the manufacturer's current catalog. Cross-reference the date code to ensure compatibility with current manufacturing standards.

Selection Notes

Select this component for designs requiring a self-contained VCO solution in the 868 MHz range. The integrated 50 Ohm output simplifies impedance matching requirements compared to discrete solutions. Consider the -40°C to +85°C temperature range for industrial environments. Evaluate the low current consumption of 11.5 mA for battery-powered applications.

Part Context

This part belongs to the MAX2622/MAX2623/MAX2624 family of self-contained voltage-controlled oscillators. These devices combine an oscillator core and output buffer in a single miniature package. The series is designed to simplify RF front-end design by reducing external component count. The MAX2622 variant specifically targets the European ISM band frequencies.

Replacement Considerations

The MAX2623EUA-T and MAX2624EUA-T are related parts within the same family but operate at different frequency ranges. Verify that the target application frequency aligns with the 855-881 MHz range of the MAX2622 before substituting with other variants.
