Description and Introduction

315MHz/434MHz Low-Power, 3V/5V ASK/FSK Superheterodyne Receiver The MAX1471ATJ+ is a low-power, CMOS, ASK/FSK superheterodyne receiver manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Frequency Range:** 300MHz to 450MHz  
- **Modulation:** ASK (Amplitude Shift Keying) / FSK (Frequency Shift Keying)  
- **Sensitivity:** -114dBm (for ASK, 2.4kbps)  
- **Supply Voltage:** 2.7V to 3.6V  
- **Current Consumption:** 5.3mA (typical in receive mode)  
- **Data Rate:** Up to 100kbps  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 32-pin TQFN (5mm x 5mm)  

### **Descriptions:**  
- The MAX1471ATJ+ is designed for low-power wireless applications, including remote keyless entry (RKE), home automation, and industrial control systems.  
- It integrates a complete superheterodyne receiver with an image-rejecting mixer, IF amplifier, and demodulator.  
- Supports both ASK and FSK modulation for flexible system design.  
- Features an automatic frequency control (AFC) loop for stable operation.  

### **Features:**  
- **Low Power Consumption:** Optimized for battery-powered applications.  
- **Integrated IF Filter:** Eliminates the need for external SAW filters.  
- **Image-Rejecting Mixer:** Improves sensitivity and reduces interference.  
- **RSSI Output:** Provides received signal strength indication.  
- **Wide Supply Range:** Operates from 2.7V to 3.6V.  
- **Small Footprint:** 32-pin TQFN package for space-constrained designs.
