Description and Introduction

2.4GHz 802.11b Zero-IF Transceivers The MAX2820AETM+ is a transceiver IC manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX2820AETM+  
- **Type:** RF Transceiver  
- **Frequency Range:** 2.4 GHz to 2.5 GHz  
- **Modulation:** Supports IEEE 802.11b/g standards  
- **Supply Voltage:** 2.7V to 3.6V  
- **Current Consumption:**  
  - Receive Mode: 45 mA (typical)  
  - Transmit Mode: 280 mA (typical at +15 dBm output)  
- **Output Power:** Up to +15 dBm  
- **Receiver Sensitivity:** -82 dBm (for 11 Mbps, 8% PER)  
- **Package:** 48-pin TQFN (7mm x 7mm)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX2820AETM+ is a fully integrated, single-chip RF transceiver designed for 2.4 GHz IEEE 802.11b/g wireless LAN applications. It integrates a direct conversion receiver, a transmitter with a power amplifier, a voltage-controlled oscillator (VCO), and a synthesizer, reducing the need for external components.  

### **Features:**  
- **Integrated Power Amplifier (PA)** with up to +15 dBm output power.  
- **Direct Conversion Receiver** for improved sensitivity and reduced external filtering.  
- **On-Chip VCO and Synthesizer** for frequency generation.  
- **Low-Noise Amplifier (LNA)** for improved receiver sensitivity.  
- **I/Q Baseband Interface** for direct connection to baseband processors.  
- **Low-Power Modes** for power-sensitive applications.  
- **Fully Compliant** with IEEE 802.11b/g standards.  

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