Description and Introduction

Miniature Electronically Trimmable Capacitor The MAX1474AXT+ is a highly integrated, low-power CMOS transceiver designed for use in the 300MHz to 450MHz frequency range. It is manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Frequency Range:** 300MHz to 450MHz  
- **Modulation:** ASK/OOK (Amplitude Shift Keying/On-Off Keying)  
- **Data Rate:** Up to 100kbps  
- **Supply Voltage:** 2.1V to 3.6V  
- **Low Power Consumption:**  
  - **Shutdown Current:** <1µA  
  - **Standby Current:** 1.5µA (typical)  
  - **Active Receive Current:** 5.7mA (typical)  
  - **Active Transmit Current:** 9.5mA (typical at +5dBm output)  
- **Output Power:** Adjustable up to +5dBm  
- **Sensitivity:** -110dBm (for 10⁻³ BER at 10kbps)  
- **Package:** 20-pin TQFN (5mm x 5mm)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions and Features:**  
- **Integrated RF Transceiver:** Combines transmitter, receiver, and synthesizer in a single chip.  
- **Low-Power Operation:** Optimized for battery-powered applications.  
- **Programmable Features:** Adjustable output power, data rate, and frequency.  
- **Crystal Oscillator Interface:** Supports an external crystal for frequency stability.  
- **Digital RSSI (Received Signal Strength Indicator):** Provides signal strength feedback.  
- **Automatic Frequency Control (AFC):** Helps maintain frequency accuracy.  
- **Small Form Factor:** Suitable for space-constrained designs.  
- **Applications:** Remote keyless entry (RKE), tire pressure monitoring (TPMS), home automation, and industrial wireless controls.  

This device is designed for reliable, low-power wireless communication in industrial and consumer applications.
