Description and Introduction

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

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Package:** 32-pin TQFN (Thin Quad Flat No-Lead)  
- **Operating Voltage:** 2.7V to 3.3V  
- **Frequency Range:** 300MHz to 450MHz  
- **Sensitivity:** -114dBm (for 12.5kHz channel bandwidth)  
- **Current Consumption:** 5.3mA (typical in receive mode)  
- **IF Frequency:** 10.7MHz  
- **Data Rate:** Up to 100kbps  

### **Descriptions:**
The MAX1471ATJ is designed for low-power wireless applications, such as remote keyless entry (RKE), tire pressure monitoring systems (TPMS), and industrial control. It integrates a complete superheterodyne receiver with an image-rejecting front end, eliminating the need for external SAW filters. The device supports ASK and FSK modulation schemes.

### **Features:**
- **Low Power Consumption:** Optimized for battery-powered applications.  
- **Integrated IF Filter:** No external IF filter required.  
- **Image-Rejecting Mixer:** Reduces the need for external filtering.  
- **Programmable Data Rate:** Supports up to 100kbps.  
- **RSSI Output:** Provides received signal strength indication.  
- **Automatic Frequency Control (AFC):** Compensates for crystal inaccuracies.  
- **Shutdown Mode:** Reduces power consumption when inactive.  

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