MAX2741ETI

RF Receivers Overview

The MAX2741ETI is an integrated L1-band GPS receiver IC designed for mobile handsets, PDAs, and automotive applications. It provides a high-performance, compact solution with a total voltage gain of 80dB and a cascaded noise figure of 4.7dB. The device supports all popular handset reference frequencies up to 26MHz and tolerates -90dBm in-band jammers and +13dBm CDMA out-of-band jammers at the device input. It features an integrated synthesizer, VCO, and 2- or 3-bit ADC, along with a 50dB IF AGC range. Operating within a supply voltage range of 2.7V to 3V, it is compatible with single-cell Li-ion batteries.

RF Receivers Procurement Notes

Verify the specific suffix (e.g., ETI, ETI+, ETI+T) against the official Analog Devices datasheet to ensure correct package type and tape/reel configuration. Confirm that the component meets RoHS compliance requirements if specified by the project standards. Cross-reference the manufacturer part number with the latest product status page to check for obsolescence or lifecycle changes before finalizing procurement plans.

RF Receivers Selection Notes

Select this component for applications requiring high sensitivity (-185dBW) for indoor tracking solutions. Ensure the design accommodates the 2.7V to 3V supply voltage range and integrates with baseband processors via the SPI control interface. Consider the 28-pin Thin QFN package constraints for PCB layout. Verify compatibility with the required reference frequency up to 26MHz and assess jamming environments to leverage the device's high interference tolerance capabilities.

RF Receivers Part Context

The MAX2741ETI belongs to the MAX2741 family of integrated GPS receivers from Maxim Integrated (now Analog Devices). This series is optimized for mobile and automotive markets, offering a balance of performance and size. The ETI variant specifically denotes the 28-pin Thin QFN package version, distinguishing it from evaluation kits or other packaging options within the same functional family.
