MAX2119CTI+

Overview

The MAX2119CTI+ is a direct-conversion satellite tuner from Analog Devices Inc./Maxim Integrated, designed for DVB-S applications. It operates within a frequency range of 950 MHz to 2150 MHz and supports a tuning bandwidth up to 1200 MHz. The device integrates a low-noise amplifier (LNA), mixer, and local oscillator, requiring only external components for filtering. It functions on a single 3.3 V supply voltage and is housed in a compact 28-lead TQFN package with an exposed pad.

Feature Summary

• Integrates LNA, mixer, and synthesizer for simplified circuit design
• Supports high-speed digital control interfaces for configuration
• Optimized for low noise figure and linearity in satellite reception

Applications

• DVB-S satellite receivers
• Satellite set-top boxes
• Direct broadcast satellite systems

Procurement Notes

Verify the specific suffix 'CTI+' against the official datasheet to confirm package type and temperature range. Ensure compatibility with system voltage requirements and interface standards before integration. Confirm availability status as distribution may vary.

Selection Notes

Select this component for designs requiring a fully integrated direct-conversion solution for Ku-band satellite signals. Consider the 28-TQFN footprint for space-constrained PCB layouts. Evaluate thermal performance due to the exposed pad requirement for adequate heat dissipation during operation.

Part Context

This part belongs to the Maxim Integrated satellite tuner family, which provides complete RF front-end solutions. These devices are engineered to reduce bill-of-materials count by integrating critical RF blocks into a single chip, facilitating easier manufacturing and improved performance consistency compared to discrete implementations.

Replacement Considerations

Check for MAX2112 variants or other Maxim Direct Conversion Tuners with similar frequency ranges. Verify pin-to-pin compatibility and register-level software compatibility if substituting within the same product family.
