MAX2424EAI

RF Transceiver ICS Overview

The MAX2424EAI is a highly integrated front-end receiver IC designed for 900MHz cordless telephones and ISM band radios. It features a 35dB image rejection mixer, adjustable gain LNA, and low power consumption. Operating on a single +2.7V to +4.8V supply, it supports FSK, BPSK, and QPSK modulation schemes. The device includes an on-chip local oscillator with a divide-by-64/65 dual-mode prescaler and offers three independent shutdown inputs for system power management.

RF Transceiver ICS Feature Summary

• Integrates a 35dB image rejection mixer to reduce filter costs
• Includes an adjustable gain low-noise amplifier (LNA)
• Features an on-chip local oscillator with dual-mode prescaler
• Supports multiple modulation schemes including FSK, BPSK, and QPSK

RF Transceiver ICS Applications

• Cordless telephones
• ISM band radios
• Frequency hopping communication systems
• Wireless telemetry applications
• Two-way paging systems

RF Transceiver ICS Procurement Notes

Verify the specific suffix 'EAI' against the official Analog Devices datasheet to confirm package type and temperature range. Ensure compatibility with required modulation standards such as FSK or BPSK. Check for end-of-life status or obsolescence notices from the manufacturer before finalizing procurement plans.

RF Transceiver ICS Selection Notes

Select this component for cost-effective 900MHz reception where image rejection is critical. It is suitable for designs requiring direct connection to three-cell battery stacks due to its voltage range. Consider the integrated LO and prescaler if external frequency synthesis components are to be minimized in the bill of materials.

RF Transceiver ICS Part Context

This part belongs to the MAX244x family of highly integrated front-end receivers. It shares architectural similarities with the MAX2440, MAX2441, and MAX2442, offering similar performance characteristics for 900MHz applications. The family provides a low-cost solution for ISM band radio designs requiring high linearity and low noise figure.

RF Transceiver ICS Replacement Considerations

The MAX2442EAI is a compatible alternative within the same product family. Verify pinout compatibility and functional equivalence regarding image rejection and modulation support when substituting.
