MAX2365EGM

RF Transmitter Overview

The MAX2365EGM is a dual-band quadrature RF transmitter IC designed for IoT applications, operating within the 1.7 GHz to 2.0 GHz frequency range. It features an integrated PLL frequency synthesizer and power amplifier, delivering up to 9 dBm output power with a transmission current of approximately 90 mA. The device supports supply voltages between 2.7 V and 3.3 V and operates reliably across a temperature range of -40°C to +85°C. Packaged in a compact 48-WFQFN (7x7 mm) surface-mount footprint with exposed pad, it utilizes standard SPI bus configuration for precise control over VCO tuning, modulation shaping, and output power levels.

RF Transmitter Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeits. Confirm RoHS compliance status and check for recent product change notices or obsolescence alerts from Analog Devices/Maxim Integrated. Ensure packaging integrity matches the 48-WFQFN specification during receipt inspection.

RF Transmitter Selection Notes

Select this component when designing systems requiring integrated quadrature transmission in the sub-2 GHz ISM bands. Consider the 48-pin QFN package constraints for PCB layout and thermal management. Verify that the host microcontroller can support the required SPI communication protocol for register configuration and dynamic parameter adjustment.

RF Transmitter Part Context
