MAX2117CTI+

Overview

The MAX2117CTI+ is a direct-conversion RF tuner integrated circuit designed for MMDS and WCS applications. It operates within a frequency range of 470 MHz to 1 GHz. The device functions on a supply voltage between 3 V and 3.6 V, with a typical operating current of 50 mA at 3.3 V. It supports data rates up to 622 Mb/s and utilizes an 80 MHz clock frequency. The component is housed in a 28-TQFN (5x5) surface-mount package and is rated for operation between -40°C and +85°C.

Feature Summary

• Direct-conversion architecture for MMDS and WCS signal tuning
• Integrated low-noise amplifier and mixer stages
• On-chip programmable gain control for signal optimization

Applications

• Multichannel Multipoint Distribution Service (MMDS) receivers
• Wireless Local Loop (WLL) systems
• Fixed wireless access terminals

Procurement Notes

Verify the specific suffix 'CTI+' against the manufacturer's official datasheet to confirm pinout and thermal specifications. Ensure compatibility with the target PCB footprint and reflow profile requirements. Confirm RoHS compliance status through the latest product trade compliance documentation provided by Analog Devices.

Selection Notes

Select this component for applications requiring direct downconversion of MMDS or WCS signals. Evaluate the 28-TQFN package size against available board space. Consider the 3V to 3.6V supply range when designing the power management section. Verify that the 470MHz to 1GHz frequency coverage aligns with the intended regulatory band.

Part Context

This part belongs to the Maxim Integrated family of RF tuners. It serves as a specialized solution for fixed wireless communication systems. The design integrates multiple RF stages into a single compact package to reduce system complexity. It represents a transition from discrete RF front-end designs to highly integrated solutions.

Replacement Considerations

Consult the official cross-reference list for direct substitutes. Generic replacements may not match the specific direct-conversion topology or frequency range. Verify pin-to-pin compatibility before substitution.
