- **Frequency Range:** 2.4GHz to 2.5GHz (optimized for ISM band)  
- **Noise Figure:** 1.6dB (typical)  
- **Gain:** 15.5dB (typical)  
- **Supply Voltage (VCC):** +2.7V to +3.3V  
- **Current Consumption:** 3.5mA (typical)  
- **Input IP3 (Third-Order Intercept Point):** -3dBm (typical)  
- **Input P1dB (Compression Point):** -12dBm (typical)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +85°C  

### **Description:**  
The MAX2690EUB is a low-noise amplifier designed for 2.4GHz to 2.5GHz wireless applications, including Bluetooth®, ZigBee®, and other ISM-band systems. It provides high gain and low noise figure while consuming minimal power, making it suitable for battery-operated devices.  

### **Features:**  
- Ultra-low noise figure (1.6dB) for improved sensitivity  
- Low power consumption (3.5mA typical)  
- Integrated shutdown mode (<1µA current)  
- Single-supply operation (2.7V to 3.3V)  
- Internal input and output matching for ease of design  
- Small µMAX package (10-pin, 3mm x 5mm)  
- Optimized for 50Ω systems  

This information is strictly based on the manufacturer's datasheet and technical documentation.
