Description and Introduction

315MHz/433MHz ASK Superheterodyne Receiver with Extended Dynamic Range The MAX1473ETJ+ is a highly integrated, low-power CMOS superheterodyne receiver designed and manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Frequency Range:** 300MHz to 450MHz  
- **Modulation Support:** ASK, FSK, and OOK  
- **Sensitivity:** -114dBm (for 12.5kHz bandwidth, 10⁻³ BER)  
- **Supply Voltage:** 2.7V to 3.3V  
- **Current Consumption:** 5.3mA (typical in receive mode)  
- **IF Bandwidth:** Programmable (455kHz or 10.7MHz)  
- **Package:** 32-pin TQFN (5mm x 5mm)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX1473ETJ+ is optimized for low-power wireless applications, including remote keyless entry (RKE), tire pressure monitoring (TPMS), and industrial telemetry. It integrates an LNA, mixer, PLL, VCO, and baseband processing, reducing external component count.  

### **Features:**  
- **Low Power Consumption:** Ideal for battery-operated devices.  
- **High Integration:** Includes on-chip VCO and PLL for reduced BOM.  
- **Programmable Data Rate:** Supports up to 100kbps.  
- **Image-Rejecting Architecture:** Improves interference rejection.  
- **RSSI Output:** Provides received signal strength indication.  
- **Shutdown Mode:** Reduces power consumption when inactive.
