### **Specifications:**
- **Frequency Range:** 433.92 MHz  
- **Modulation:** ASK (Amplitude Shift Keying)  
- **Supply Voltage:** 2.1 V to 4 V  
- **Current Consumption:**  
  - Standby: < 1 µA  
  - Transmit: ~ 10 mA (typical)  
- **Output Power:** Up to +10 dBm (adjustable)  
- **Data Rate:** Up to 20 kbps  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** P-TSSOP-14  

### **Descriptions:**
- The TDA5101 is a low-power RF transmitter designed for wireless applications such as remote keyless entry (RKE), garage door openers, and alarm systems.
