Description and Introduction

300MHz to 450MHz Low-Power, Crystal-Based +10dBm ASK/FSK Transmitter The MAX1479ATE is a 315MHz/433MHz ASK/FSK superheterodyne receiver manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Frequency Range:** 315MHz or 433MHz (selectable)  
- **Modulation Types:** ASK (Amplitude Shift Keying) and FSK (Frequency Shift Keying)  
- **Sensitivity:** -114dBm (ASK mode), -110dBm (FSK mode)  
- **Supply Voltage Range:** 2.7V to 3.6V  
- **Current Consumption:** 5.3mA (typical in receive mode)  
- **IF Frequency:** 10.7MHz  
- **Data Rate:** Up to 100kbps (ASK), Up to 20kbps (FSK)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin TQFN (5mm x 5mm)  

### **Descriptions:**
The MAX1479ATE is a low-power, high-performance superheterodyne receiver designed for wireless applications in the 315MHz and 433MHz ISM bands. It supports both ASK and FSK modulation schemes, making it versatile for various remote control and data transmission applications. The device integrates an LNA (Low-Noise Amplifier), mixer, IF amplifier, demodulator, and data filter, reducing external component count.

### **Features:**
- **Low Power Consumption:** 5.3mA typical receive current  
- **High Sensitivity:** -114dBm (ASK), -110dBm (FSK)  
- **Selectable Frequency:** 315MHz or 433MHz operation  
- **Integrated IF Filter:** Reduces external component requirements  
- **Wide Supply Range:** 2.7V to 3.6V operation  
- **Small Footprint:** 16-pin TQFN package (5mm x 5mm)  
- **FSK and ASK Demodulation:** Supports both modulation types  
- **RSSI Output:** Received Signal Strength Indicator for signal monitoring  
- **Low External Component Count:** Simplifies design  

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

- **Data Rate:** Up to 100kbps  
- **Modulation Support:** ASK, FSK, and OOK  
- **IF Frequency:** 10.7MHz  
- **Package:** 16-pin TQFN (5mm x 5mm)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Features:**  
- Integrated IF filter and demodulator  
- Low-power shutdown mode (0.1µA typical)  
- Programmable data slicer for improved noise immunity  
- Automatic frequency control (AFC) for FSK reception  
- RSSI (Received Signal Strength Indicator) output  
- On-chip oscillator with external crystal support  

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

The MAX1479ATE is optimized for battery-powered applications requiring high sensitivity and low power consumption.
