- **Current Consumption:** **50 mA** (typical)  
- **Input/Output Impedance:** **50 Ω**  

### **Descriptions:**
The **MAX243ESE+** is a **low-noise amplifier (LNA)** designed for **RF applications** up to **2.5 GHz**. It provides high gain with low noise figure, making it suitable for **wireless communication systems**, **cellular infrastructure**, and **RF front-end circuits**. The device operates from a single **+5V supply** and is housed in a **16-pin SOIC package**.

### **Features:**
- **Wideband operation** (up to 2.5 GHz)  
- **High gain (15 dB)** for signal amplification  
- **Low noise figure (3.5 dB)** for improved signal integrity  
- **Single +5V supply operation**  
- **50 Ω input/output impedance** for easy integration  
- **Robust performance** across industrial temperature ranges (-40°C to +85°C)  

This device is commonly used in **RF receivers, transceivers, and signal conditioning circuits** where high gain and low noise are critical.
