概述

Description

MAX2771ETI+T is a Maxim Integrated RF transceiver IC for wireless applications, designed to deliver a compact, highly integrated front-end solution. It typically combines an RF/IF front end, mixers, a PLL/synthesizer, and a digital control interface in one chip, enabling simplified radio design with programmable TX/RX paths and adjustable gain. The ETI+T suffix indicates specific packaging/temperature/tape options; exact package and operating conditions vary by lot—check the latest datasheet for details. Key performance points (frequency range, NF, IP3, Pout, current consumption) are specified in the datasheet and should be verified for your target band. Common applications include wireless infrastructure front-ends, RF transceivers for point-to-point links, and RF test equipment. For precise specs and package options, consult the MAX2771 datasheet and contact the vendor if needed. If you share your target frequency band and interface needs, I can tailor the summary further.

Features

Here are the key features of the MAX2771ETI+T evaluation kit:
- Fully integrated 2.4 GHz RF transceiver front-end (Tx/Rx) with internal PLL/VCO
- On-board 50-ohm RF matching network and balun for easy RF interfacing
- Programmable TX power and RX gain via control interface
- SPI (or similar) control interface with register map for quick MCU integration
- On-board reference clock options and robust LO generation
- USB-powered interface for power and data, plus PC GUI for quick testing
- Evaluation board includes SMA RF connectors, headers, and antenna options
- Comes with software tools, reference designs, and documentation
- Suitable for ZigBee/IEEE 802.15.4 and other 2.4 GHz ISM applications
- Low-power operation with multiple power modes for testing and prototyping
- RoHS-compliant, ready-to-use evaluation platform with clear, concise setup
Note: For exact specifications, pinouts, and supported features, refer to the MAX2771 datasheet and the ETI+T kit documentation.

Package

MAX2771ETI+T is offered in a 28-pin TQFP (Thin Quad Flat Package), lead-free (RoHS-compliant).

Pinout

- Pin count: 28 pins (in the ETI+T package).
- Function: RF frequency synthesizer/front-end IC used in wireless transceivers (provides PLL/VCO control, RF I/O, and a digital interface for configuration).

Manufacturer

Manufacturer: Maxim Integrated (the MAX2771ETI+T is a Maxim part; Maxim was acquired by Analog Devices in 2021).
What kind of company: Maxim Integrated is a semiconductor company that designs and supplies analog and mixed-signal integrated circuits (power management, signal conditioning, data converters, interface ICs and related products) for automotive, industrial, communications and consumer markets.

Application

MAX2771ETI+T is a high-performance RF frequency synthesizer used in wireless transceivers. Typical applications include base stations and small cells, point-to-point microwave links, RF front-ends for mobile/IoT, satellite communications, radar (including automotive radar), and test equipment requiring precise LO generation.

Equivalent

I don’t have a reliable cross-reference for MAX2771ETI+T without its datasheet. Please share the chip’s function and key specs (frequency range, gain, package, supply voltage), or allow me to look it up — then I can list compatible pin‑for‑pin or functional equivalents (from ADI, TI, NXP, Skyworks, etc.).
