Description and Introduction

315MHz/433MHz ASK Superheterodyne Receiver with Extended Dynamic Range The MAX1473EUI+T is a highly integrated, low-power CMOS superheterodyne receiver designed for 300MHz to 450MHz frequency bands. It is manufactured by Maxim Integrated (now part of Analog Devices).  

### **Key Specifications:**  
- **Frequency Range:** 300MHz to 450MHz  
- **Supply Voltage:** 2.7V to 3.3V  
- **Current Consumption:** 5.3mA (typical) in receive mode  
- **Sensitivity:** -114dBm (for 10⁻³ BER at 10kbps)  
- **Data Rate:** Up to 100kbps  
- **Modulation Support:** ASK (Amplitude Shift Keying)  
- **IF Frequency:** 10.7MHz  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin TSSOP (Thin Shrink Small Outline Package)  

### **Key Features:**  
- **Low Power Consumption:** Optimized for battery-powered applications.  
- **Integrated IF Filter:** Eliminates the need for external SAW filters.  
- **Automatic Gain Control (AGC):** Improves dynamic range.  
- **Image-Rejecting Mixer:** Reduces interference from image frequencies.  
- **RSSI (Received Signal Strength Indicator):** Provides signal strength measurement.  
- **Low-Noise Amplifier (LNA):** Enhances sensitivity.  
- **Digital Tuning:** Allows flexible frequency selection.  

### **Applications:**  
- Remote keyless entry (RKE)  
- Tire pressure monitoring systems (TPMS)  
- Home automation  
- Wireless sensor networks
