Description and Introduction

1300MHz to 2700MHz Variable-Gain Amplifier with Analog Gain Control The MAX2057ETX is a high-performance, digitally controlled variable gain amplifier (VGA) manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX2057ETX  
- **Package:** 36-Pin TQFN (Thin Quad Flat No-Lead)  
- **Operating Frequency Range:** 50MHz to 4000MHz (4GHz)  
- **Gain Control Range:** 30dB (typical)  
- **Noise Figure:** 5.5dB (typical at maximum gain)  
- **Output IP3 (Third-Order Intercept):** +30dBm (typical)  
- **Supply Voltage:** +3.3V to +5V  
- **Current Consumption:** 85mA (typical)  
- **Digital Gain Control Interface:** 3-Wire SPI (Serial Peripheral Interface)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX2057ETX is a broadband, digitally controlled VGA designed for applications requiring precise gain adjustment over a wide frequency range. It is suitable for wireless infrastructure, test equipment, and other high-frequency systems. The device integrates a high-linearity amplifier with a digital control interface for accurate gain settings.

### **Features:**  
- **Wideband Operation:** Supports frequencies from 50MHz to 4GHz.  
- **High Linearity:** Delivers high OIP3 (Output Third-Order Intercept) for improved signal integrity.  
- **Low Noise Figure:** Ensures minimal signal degradation.  
- **SPI-Programmable Gain:** Allows precise digital control of gain settings.  
- **Single-Supply Operation:** Works with +3.3V or +5V supplies.  
- **Compact Package:** 36-pin TQFN for space-constrained designs.  
- **Integrated Power Detector:** Enables closed-loop power control.
