MAX2023ETX

Overview

The MAX2023ETX is a high-dynamic-range quadrature modulator and demodulator designed for direct up- and downconversion applications. It operates within a frequency range of 1500 MHz to 2300 MHz, supporting wireless standards including CDMA, EDGE, GSM, and TDMA. The device is housed in a 36-TQFN (6x6) package with an exposed pad for thermal management. It functions as a versatile RF IC suitable for mixed-signal communication systems requiring precise signal conversion.

Feature Summary

• Direct up-conversion and down-conversion architecture for simplified system design
• High dynamic range performance for improved signal integrity

Procurement Notes

Verify component status carefully as the MAX2023 series may be classified as obsolete or discontinued by Analog Devices. Confirm availability through authorized distributors and check for valid RoHS compliance documentation. Ensure the specific suffix matches the required packaging format, such as tube or reel, before finalizing procurement orders.

Selection Notes

Select this component for applications requiring direct conversion between baseband and RF frequencies in the 1.5 GHz to 2.3 GHz band. Consider the 36-TQFN package size for PCB layout constraints. Evaluate thermal requirements due to the exposed pad design. Ensure compatibility with supported digital modulation standards like GSM and CDMA during system integration.

Part Context

The MAX2023 belongs to the Maxim Integrated RF IC family focused on wireless communication solutions. It serves as a specialized modulator/demodulator for cellular infrastructure and handsets. The part integrates essential RF functions into a compact surface-mount package, reducing external component count compared to traditional superheterodyne architectures.
