Description and Introduction

300MHz-to-450MHz Low-Power, Crystal-Based ASK Transmitter The MAX1472AKA is a low-power, CMOS superheterodyne receiver manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Frequency Range:** 300MHz to 450MHz  
- **Supply Voltage:** 2.7V to 3.3V  
- **Current Consumption:** 5.3mA (typical)  
- **Sensitivity:** -114dBm (for 12dB SINAD)  
- **IF Frequency:** 10.7MHz  
- **Image Rejection:** 40dB (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
- The MAX1472AKA is a fully integrated, low-power ASK/FSK receiver designed for wireless applications.  
- It includes an LNA (Low-Noise Amplifier), mixer, PLL (Phase-Locked Loop), VCO (Voltage-Controlled Oscillator), and baseband processing circuitry.  
- Suitable for remote keyless entry (RKE), home automation, and industrial wireless control systems.  

### **Features:**  
- **Low Power Consumption:** Optimized for battery-operated devices.  
- **High Sensitivity:** Enables reliable reception in weak signal conditions.  
- **Integrated IF Filter:** Eliminates the need for external SAW filters.  
- **Image Rejection:** Reduces interference from adjacent channels.  
- **ASK/FSK Demodulation:** Supports both modulation schemes.  
- **Small Footprint:** 8-pin SOIC package for space-constrained designs.
