MAX2751EUA

Overview

The MAX2751EUA is a monolithic voltage-controlled oscillator (VCO) designed for ISM band applications, specifically operating at 2.4 GHz. Manufactured by Analog Devices Inc./Maxim Integrated, this component integrates the VCO core and tuning elements into a single chip to simplify RF circuit design. It is housed in an 8-uMAX surface-mount package, providing a compact solution for wireless communication systems requiring stable frequency generation within the 2.4 GHz spectrum.

Feature Summary

• Integrates voltage-controlled oscillator functionality on a single monolithic chip
• Designed for operation in the 2.4 GHz ISM band
• Utilizes a compact 8-pin uMAX surface-mount package

Applications

• Wireless local area network (WLAN) transceivers
• Bluetooth low energy (BLE) modules
• ISM band radio frequency identification (RFID) readers

Procurement Notes

Verify current manufacturing status as the MAX2751EUA may be obsolete or restricted. Confirm availability through authorized distributors or check for direct substitutes if production has ceased. Ensure compatibility with existing PCB layouts and thermal requirements before procurement.

Selection Notes

Select this component for designs requiring a pre-tuned 2.4 GHz oscillator without external inductors. Consider the 8-uMAX package size for space-constrained applications. Evaluate phase noise and tuning linearity specifications against system requirements for signal integrity.

Part Context

Part of the MAX275x series of monolithic VCOs from Maxim Integrated, now part of Analog Devices. This family targets simplified RF front-end designs for short-range wireless communications, offering integrated solutions that reduce component count and board area compared to discrete VCO implementations.

Replacement Considerations
