MAX2361EGM

RF Transmitter Overview

The MAX2361EGM is a dual-band, triple-mode complete quadrature transmitter IC designed for cellular handsets. It integrates an I/Q modulator, dual IF VGAs, and a PLL frequency synthesizer with a VCO. The device operates in the 120MHz to 235MHz and 824MHz to 960MHz bands, supporting GSM, DCS, PCS, and WCDMA modes. Key electrical parameters include a supply voltage of 3.3V, operating frequency range up to 1.7GHz-2GHz, and SPI data interface. It is housed in a 48-VFQFN exposed pad package.

RF Transmitter Feature Summary

• Integrates I/Q modulator, dual IF VGAs, and PLL/VCO for complete transmission functionality
• Supports dual-band operation covering GSM/DCS/PCS and WCDMA standards
• Features programmable gain control and digital calibration via SPI interface

RF Transmitter Applications

• Cellular handset transmitters
• GSM/DCS/PCS baseband processing modules
• WCDMA mobile communication devices

RF Transmitter Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot codes and date stamps match current production batches. Ensure RoHS compliance documentation is provided. Check for potential obsolescence status as older Maxim Integrated products may have limited long-term availability compared to newer alternatives.

RF Transmitter Selection Notes

Select this component for applications requiring integrated quadrature modulation in compact form factors. Consider thermal performance due to RF power dissipation in the QFN package. Verify compatibility with existing baseband processor SPI interfaces. Evaluate board space constraints against the 48-pin footprint requirements.

RF Transmitter Part Context

Part of Maxim Integrated's (now Analog Devices) portfolio of RF transceivers for mobile communications. Designed to reduce bill-of-materials count by integrating multiple RF functions into a single chip. Represents legacy technology for 2G and early 3G cellular platforms before widespread adoption of highly integrated SoCs.
