Description and Introduction

0.4 GHz to 4.0 GHz Quadrature Modulator, 1.7V common-mode voltage 24-VQFN -40 to 85 The TRF370317IRGET is a high-performance, direct quadrature modulator from Texas Instruments (TI)/Burr-Brown (BB).  

**Specifications:**  
- **Frequency Range:** 400 MHz to 4000 MHz  
- **Supply Voltage:** 3.3 V  
- **Current Consumption:** 105 mA (typical)  
- **LO Input Frequency Range:** 400 MHz to 4000 MHz  
- **Sideband Suppression:** -50 dBc (typical)  
- **Carrier Leakage:** -40 dBm (typical)  
- **Output Power:** -5 dBm (typical)  
- **Package:** 24-VQFN (4x4 mm)  

**Descriptions:**  
The TRF370317IRGET is designed for wireless communication applications, providing high linearity and low noise performance. It integrates an LO buffer, I/Q modulator, and output amplifier, simplifying RF signal chain design.  

**Features:**  
- High linearity with OIP3 of 30 dBm (typical)  
- Integrated LO buffer with single-ended input  
- Low LO leakage and sideband suppression  
- Wide LO and RF frequency range  
- Small footprint for space-constrained designs  
- Operates from a single 3.3 V supply  

This device is suitable for applications such as cellular infrastructure, microwave backhaul, and software-defined radios.
