Description and Introduction

350 MHz to 4.0 GHz Quadrature Modulator, 3.3V common-mode voltage 24-VQFN -40 to 85 The TRF370333 is a high-performance, wideband quadrature modulator from Texas Instruments (TI). Below are the factual specifications, descriptions, and features:

### **Manufacturer:**  
Texas Instruments (TI)  

### **Part Number:**  
TRF370333  

### **Description:**  
The TRF370333 is a direct quadrature modulator designed for wideband communication systems. It converts baseband I/Q signals to RF with high linearity and low noise, making it suitable for applications like wireless infrastructure, software-defined radios, and test equipment.  

### **Key Features:**  
- **Frequency Range:** 400 MHz to 4 GHz  
- **High Output Power:** Up to 5 dBm  
- **High Linearity:**  
  - OIP3: 30 dBm typical  
  - OIP2: 60 dBm typical  
- **Low LO Leakage:** -45 dBm typical  
- **Low Sideband Suppression:** -50 dBc typical  
- **Wide IF Bandwidth:** Supports up to 500 MHz  
- **Integrated LO Buffer:** Eliminates the need for external amplification  
- **Supply Voltage:** 3.3 V  
- **Low Power Consumption:** 175 mA typical  
- **Package:** 24-pin QFN (4 mm × 4 mm)  

### **Applications:**  
- Wireless infrastructure (LTE, 5G, etc.)  
- Software-defined radios (SDR)  
- Test and measurement equipment  
- Point-to-point microwave links  

### **Additional Notes:**  
- Requires minimal external components for operation.  
- Supports differential or single-ended LO input.  

For detailed electrical characteristics and application circuits, refer to the official TI datasheet.
