Description and Introduction

LNAs with Step Attenuator and VGA The MAX2373ETC+ is a high-performance, low-power GPS receiver IC manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual data:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX2373ETC+  
- **Package:** TQFN-12 (3mm x 3mm)  
- **Operating Voltage Range:** 2.7V to 3.3V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Frequency Range:** 1575.42MHz (GPS L1 Band)  
- **Noise Figure:** 1.8dB (typical)  
- **Gain:** 15.5dB (typical)  
- **Input IP3 (Third-Order Intercept Point):** -11dBm  
- **Current Consumption:** 4.5mA (typical)  
- **RF Input Impedance:** 50Ω  
- **RF Output Impedance:** 50Ω  

### **Description:**  
The MAX2373ETC+ is a compact, low-noise amplifier (LNA) designed for GPS applications. It provides high gain and low noise figure, making it suitable for weak signal reception in GPS systems. The device operates from a single low-voltage supply and is optimized for minimal power consumption while maintaining high linearity.

### **Features:**  
- Low noise figure (1.8dB typical) for improved sensitivity  
- High gain (15.5dB typical) for signal amplification  
- Low power consumption (4.5mA typical)  
- Single 2.7V to 3.3V supply operation  
- Small 12-pin TQFN package (3mm x 3mm)  
- Integrated 50Ω input and output matching  
- High linearity (IP3 of -11dBm)  
- Wide operating temperature range (-40°C to +85°C)  

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