MAX2223ETI+

Overview

The MAX2223ETI+ is an ultra-wideband, direct-conversion L-band satellite tuner IC designed for satellite set-top and VSAT applications. It operates within a frequency range of 925 MHz to 2.175 GHz. The device integrates an LNA, RF variable-gain amplifier, I/Q down-converting mixers, baseband amplifiers, and fully monolithic VCOs. It features a VCO auto-select function that automatically selects the proper VCO. The component requires a 3.3 V operating supply voltage and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Direct-conversion architecture with integrated LNA, mixers, and baseband amplifiers
• VCO auto-select function for automatic oscillator selection
• Ultra-wideband L-band coverage from 925 MHz to 2.175 GHz
• Fully monolithic VCO integration

Applications

• Satellite set-top boxes
• Very Small Aperture Terminal (VSAT) systems

Procurement Notes

Verify the exact part number MAX2223ETI+ against official Analog Devices documentation to ensure compatibility with L-band satellite tuner requirements. Confirm package type is 28-TQFN (5x5). Check supply voltage specifications match system design at 3.3 V. Validate operating temperature range covers -40°C to +85°C for intended environment. Ensure application aligns with direct-conversion tuner use cases.

Selection Notes

Select this component for designs requiring direct-conversion L-band tuning in satellite receivers. Consider the integrated nature of the LNA, mixers, and VCOs for simplified circuit topology. Evaluate the 925 MHz to 2.175 GHz frequency range against signal requirements. Assess the 3.3 V supply constraint and thermal performance within the specified industrial temperature range.

Part Context

This device belongs to the family of direct-conversion tuners developed by Maxim Integrated, now part of Analog Devices. It targets the L-band spectrum specifically for satellite communication infrastructure. The integration of passive components reduces external bill of materials compared to heterodyne solutions.
