MAX2751EUA+

Product Overview

MAX2751EUA+ from Analog Devices / Maxim Integrated is a 2.4 GHz monolithic voltage-controlled oscillator used in RF, microwave or high-speed receiver signal-chain designs. This description focuses on practical RF function, operating range, interface requirements and sourcing relevance for engineering and procurement teams.

The exact suffix should be checked against the original BOM because RF performance, package, temperature range and reel format may vary across closely related orderable part numbers.

RF oscillator replacements where MAX2750/2751/2752 tuning band and µMAX footprint must be maintained.

Quality & Sourcing

Antrex Electronics can support sourcing for MAX2751EUA+ through available stock checks, BOM consolidation and alternative-lot review. For RF and microwave components, packaging condition, date code, MSL handling and original labeling should be checked before shipment.

For project builds, repair support or shortage coverage, Antrex Electronics can coordinate visual inspection, package verification and third-party testing when required. This helps buyers manage risk when sourcing discontinued, legacy or hard-to-find RF misc ICs and modules.
