MAX2622EUA+T

Overview

The MAX2622EUA+T is a monolithic voltage-controlled oscillator (VCO) from Analog Devices, operating within the European ISM band. It covers a frequency range of 855 MHz to 881 MHz with an 868 MHz center frequency. The device requires a supply voltage between 2.7 V and 5.5 V and accepts a tuning voltage of 0.4 V to 2.4 V. Key electrical parameters include a typical output power of -3 ±3 dBm, a second harmonic level of -27 dBc, and a maximum current consumption of 11.5 mA. It features on-chip 50 Ohm output matching and operates across a temperature range of -40°C to +85°C in an 8-pin uMAX package.

Feature Summary

• Integrates a self-contained oscillator and output buffer for compact design
• Includes on-chip 50 Ohm output matching to simplify circuit layout
• Operates within the European ISM band for regional compliance

Applications

• European ISM band transceiver systems
• Wireless local loop (WLL) applications
• RF signal generation circuits

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance and lead-free soldering specifications against project requirements. Validate pinout compatibility and thermal characteristics during integration. Ensure sourcing partners provide traceable documentation for quality assurance purposes.

Selection Notes

Select this component for designs requiring a fixed-frequency VCO in the 868 MHz range. Consider the narrow tuning window and specific supply voltage constraints. Evaluate the trade-off between integrated matching simplicity and fixed frequency limitations compared to programmable alternatives.

Part Context

This part belongs to the MAX262x series of voltage-controlled oscillators. It shares architectural similarities with the MAX2622 and MAX2623, offering a miniature footprint suitable for space-constrained RF modules. The series targets cost-effective solutions for specific regional frequency allocations.

Replacement Considerations

The MAX2622EUA+ is listed as a direct substitute. Verify package dimensions and pin configuration compatibility before substitution.
