### **Descriptions:**
The MAX2165ETI+T is a direct-conversion tuner designed for digital TV and radio applications. It converts RF signals directly to baseband I/Q outputs, eliminating the need for external IF SAW filters. It integrates a low-noise amplifier (LNA), mixer, variable-gain amplifier (VGA), and baseband filters, making it suitable for cable, terrestrial, and mobile TV tuners.
### **Features:**
- **Direct-Conversion Architecture** – Eliminates the need for IF SAW filters.
- **Integrated LNA, Mixer, and Baseband Filters** – Simplifies design and reduces external components.
- **Wide Frequency Range (48MHz–860MHz)** – Supports global TV standards.
- **Low Noise Figure (4.5dB typical)** – Improves sensitivity.
- **64dB Gain Control Range** – Ensures robust signal handling.
- **Low Power Consumption** – Optimized for portable applications.
- **I/Q Baseband Outputs** – Enables digital demodulation.
- **Single 3.3V Supply Operation** – Simplifies power management.
