MAX2870ETJ+

Product Overview

MAX2870ETJ+ from Analog Devices / Maxim Integrated is a fractional/integer-N synthesizer with integrated VCO 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.

Applications

Wideband RF signal generators, microwave radios, test equipment, LO synthesizers and wireless infrastructure clocks.

PLL/VCO replacements requiring the same MAX2870/MAX2871 output range, register map and TQFN footprint.

Quality & Sourcing

Antrex Electronics can support sourcing for MAX2870ETJ+ 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.
