MAX2622EUA+

Overview

The MAX2622EUA+ is a monolithic voltage-controlled oscillator (VCO) designed for the European ISM band. It operates within a frequency range of 855 MHz to 881 MHz, centered at 868 MHz. The device supports a supply voltage from 2.7 V to 5.5 V and features a tuning voltage range of 0.4 V to 2.4 V DC. It draws 12.5 mA current and delivers -8 dBm output power with -29 dBc secondary harmonics. Phase noise is specified at -110 dBc/Hz, with a push of 71 kHz/V. Operating temperature ranges from -40°C to +85°C in an 8-uMAX package.

• Integrated on-chip 50 Ohm output matching network simplifies RF design
• Low current shutdown mode reduces power consumption
• Monolithic construction ensures reliability in compact form factors

Applications

• European ISM band applications at 866 MHz to 868 MHz
• Wireless local loop transceivers
• RF signal generation circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Ensure storage conditions align with moisture sensitivity levels. Validate part markings against datasheet specifications to prevent counterfeit substitution during assembly processes.

Selection Notes

Select this component for fixed-frequency ISM band requirements where precise center frequency stability is critical. Consider the 8-uMAX package constraints for PCB layout. Evaluate thermal performance within the specified operating temperature range. Compare phase noise and harmonic suppression against system link budget requirements before finalizing the design.

Part Context

This part belongs to the MAX2620 series of integrated RF oscillators. It shares architectural similarities with other members like the MAX2620 but is optimized for specific frequency bands. The series targets cost-effective solutions for wireless communication systems requiring stable local oscillator signals without external resonators.

Replacement Considerations

The MAX2622EUA+T is a tape-and-reel variant of the same functional device. Verify packaging differences if automated pick-and-place equipment is utilized. No alternative part numbers are publicly confirmed as direct substitutes.
