Description and Introduction

GPS/GNSS Low-Noise Amplifier The MAX2659ELT+ is a low-noise amplifier (LNA) manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Frequency Range:** 1575 MHz (optimized for GPS applications)
- **Gain:** 15.5 dB (typical)
- **Noise Figure:** 1.4 dB (typical)
- **Supply Voltage (VCC):** 1.6V to 3.3V
- **Supply Current:** 3.8 mA (typical at 3.0V)
- **Input/Output Impedance:** 50 Ω
- **Operating Temperature Range:** -40°C to +85°C
- **Package:** 6-pin Thin SOT23 (TDFN)

### **Descriptions:**
- The MAX2659ELT+ is a high-performance GPS LNA designed for low-power, low-noise applications.
- It integrates a high-gain, low-noise amplifier with an active bias circuit for stable performance.
- Suitable for GPS, GLONASS, and other satellite navigation systems.

### **Features:**
- **Low Noise Figure (1.4 dB typical)** for improved sensitivity.
- **High Gain (15.5 dB typical)** to boost weak signals.
- **Low Power Consumption (3.8 mA at 3.0V).**
- **Single 1.6V to 3.3V Supply Operation** for flexibility.
- **Integrated Active Bias** for stable performance over temperature and supply variations.
- **Small 6-Pin TDFN Package** for space-constrained applications.
- **ESD Protection (up to ±2 kV HBM)** for robustness.

This LNA is commonly used in GPS receivers, satellite communication systems, and other RF applications requiring high sensitivity and low noise.
