MAX2368EGM

RF Transmitter Overview

The MAX2368EGM is a complete dual-band quadrature transmitter designed for wireless LAN and WAN applications. It integrates a fractional-N PLL, digitally controlled phase-locked loop, and power amplifier within a single 48-VFQFN exposed pad package. The device supports simultaneous operation in the 1.7GHz and 2GHz frequency ranges with supply voltages between 2.7V and 3V. Operating temperatures range from -40°C to 85°C. Key electrical parameters include an output power of 6.6dBm to 12dBm and transmit current consumption of 114mA to 132mA. Communication is managed via an SPI data interface.

RF Transmitter Feature Summary

• Combines quadrature transmitter functions with a power amplifier
• Supports reliable operation in energy-constrained portable applications

RF Transmitter Applications

• Wireless LAN (WLAN)
• Wireless WAN
• Portable wireless access points

RF Transmitter Procurement Notes

Verify the specific manufacturer source, as Analog Devices Inc. acquired Maxim Integrated. Confirm the exact suffix 'EGM' matches the required 48-VFQFN package and surface mount configuration. Ensure compatibility with CDMA modulation protocols if applicable to the target design. Check for active lifecycle status and lead time requirements directly with authorized distributors.

RF Transmitter Selection Notes

Select this component when a compact solution for dual-band transmission is required without external synthesizers. The integrated PA and PLL simplify board layout compared to discrete solutions. Consider the 2.7V to 3V supply constraint and the specific 1.7GHz/2GHz band requirements. The SPI interface must be supported by the host controller for proper configuration and control.

RF Transmitter Part Context

This part belongs to the Maxim Integrated line of RF transmitters, now under Analog Devices Inc. It serves as a specialized IC for high-frequency signal generation and amplification. The device replaces multi-component transmitter architectures by consolidating PLL, mixer, and PA functions into one surface-mount package.
