MAX2623EUA

Overview

The MAX2623EUA is a fully monolithic voltage-controlled oscillator (VCO) designed for ISM band applications. It operates within a frequency range of 885 to 950 MHz, with a center frequency of 917.5 MHz. The device supports single-supply operation from 2.7 V to 5.5 V and utilizes a tuning voltage range of 0.4 V to 2.4 V. It features an integrated on-chip 50-ohm output match and is housed in an 8-pin uMAX package.

Feature Summary

• Fully monolithic construction integrating oscillator and output buffer
• On-chip 50-ohm output matching network
• Single-supply operation capability

Applications

• ISM band transmitters
• Wireless sensor networks
• RF signal generation modules

Procurement Notes

Verify the specific suffix (e.g., +T) against the required reel quantity or tape-and-reel specifications. Confirm that the lead-free designation (+) aligns with environmental compliance requirements. Ensure the uMAX-8 package dimensions match the PCB footprint design constraints before finalizing the order.

Selection Notes

Select this component when a compact, self-contained VCO solution is required for ISM bands near 900 MHz. Consider the guaranteed performance metrics and wide frequency choice options available within the MAX2622/2623/2624 family. Evaluate the supply voltage range against the system's power budget and the tuning voltage linearity requirements for the specific modulation scheme.

Part Context

This part belongs to the MAX2622/MAX2623/MAX2624 series of self-contained voltage-controlled oscillators. These devices combine an integrated oscillator core with an output buffer to simplify RF circuit design. The series offers a wide choice of frequencies optimized for various industrial, scientific, and medical bands, providing a standardized solution for mixed-signal PCB layouts.

Replacement Considerations

The MAX2622EUA and MAX2624EUA are direct functional substitutes within the same series, offering similar monolithic VCO architectures with different center frequency optimizations.
