MAX2900ETI+T

RF Transmitter Overview

The MAX2900ETI+T is a single-chip RF transmitter IC designed for the 902MHz to 928MHz ISM band. It supports ASK, OOK, BPSK, and FM modulation protocols with an output power of 20dBm (100mW) or 25dBm depending on configuration. The device operates on a supply voltage range of 2.7V to 4.5V and features a 28-WFQFN exposed pad package. It includes integrated VCO, synthesizer, and modulator circuits.

RF Transmitter Feature Summary

• Integrates complete RF transmission chain including VCO, frequency synthesizer, and modulator in a single chip.
• Supports multiple modulation schemes including Amplitude Shift Keying (ASK), On-Off Keying (OOK), Binary Phase Shift Keying (BPSK), and Frequency Modulation (FM).
• Features an integrated fractional-N synthesizer for precise frequency control within the ISM band.

RF Transmitter Applications

• ISM band wireless sensor networks
• Remote keyless entry systems
• Wireless alarm systems

RF Transmitter Procurement Notes

Verify component status as the MAX2900 series may be subject to obsolescence notices from Analog Devices/Maxim Integrated. Confirm RoHS3 compliance and MSL level 1 classification during sourcing. Ensure the specific suffix 'T' indicates tape and reel packaging if required for automated assembly processes.

RF Transmitter Selection Notes

Select this component for applications requiring high integration in the 902-928MHz range. Consider the 28-WFQFN package for surface mount convenience. Evaluate power consumption against the 200mA typical current rating. Ensure PCB layout guidelines for mixed-signal RF designs are followed to maintain signal integrity.

RF Transmitter Part Context

This part belongs to the MAX2900 series of low-power RF transmitters. It is manufactured by Analog Devices Inc./Maxim Integrated. The device is designed to simplify RF design by integrating passive components where possible, reducing external bill of materials.
