概述

Description

MAX274AEWI is a Maxim Integrated RF front-end IC used in wireless transceivers. It’s designed to simplify RF design by integrating key RF blocks (such as front-end matching, and/or LNA/mixer paths) into a single chip, reducing external parts and board space. The “AEWI” suffix denotes a specific RoHS-compliant package variant and pinout.
Typical usage
- Targets short‑range wireless applications (e.g., 2.4 GHz ISM bands, Bluetooth/Wi‑Fi front‑ends, remote controls).
- Used where a compact, low‑power RF front end is desired to minimize external components.
What to check in the datasheet
- Exact operating frequency range, gain, and noise figure
- Supply voltage, power consumption
- External components required (filters, baluns, matching networks)
- Package type and pinout
- Evaluation kit availability and typical application circuits
If you want a precise, itemized intro, I can summarize the official datasheet or an application note if you share a link or allow me to fetch it.

Package

MAX274AEWI is in a 28-pin TQFN package (5×5 mm).

Manufacturer

Manufacturer: Maxim Integrated (now part of Analog Devices).
What kind of company: A semiconductor company that designs and manufactures analog and mixed-signal integrated circuits (originally fabless).
