MAX19985AETX+T

Product Overview

MAX19985AETX+T from Analog Devices / Maxim Integrated is a dual high-linearity downconversion mixer used for RF and microwave frequency conversion. This product detail focuses on practical mixer parameters such as RF/LO/IF range, conversion performance, linearity, drive requirements and package compatibility.

The device is suitable for receiver, transmitter, upconversion or downconversion stages where the exact suffix must be matched for package, tape-and-reel format, temperature grade and RF layout before purchase.

Applications

Wireless infrastructure, cellular base stations, microwave radios, satellite communication equipment, radar front ends, test instruments and broadband receiver or transmitter conversion paths.

Repair, prototype and shortage-support builds where original Analog Devices / Hittite / Maxim mixer suffix, package footprint and frequency plan must remain compatible with the existing RF design.

Quality & Sourcing

Antrex Electronics can support sourcing for MAX19985AETX+T through available stock checks, BOM consolidation and alternative-lot review. For RF mixer components, date code, MSL handling, original label condition and package integrity should be reviewed before shipment.

For production recovery, 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 mixer parts.
