Description and Introduction

2.4GHz to 2.5GHz Linear Power Amplifier The MAX2242 is a power amplifier (PA) designed for applications in the 2.4GHz to 2.5GHz ISM band, such as Wi-Fi and Bluetooth.  

### **Manufacturer:**  
- **MAX** (Maxim Integrated, now part of Analog Devices)  

### **Specifications:**  
- **Frequency Range:** 2.4GHz to 2.5GHz  
- **Output Power:** Up to +22.5dBm (adjustable)  
- **Power Gain:** 28dB typical  
- **Supply Voltage:** 2.7V to 3.6V  
- **Current Consumption:** 110mA (typical at +22.5dBm output)  
- **Efficiency:** 40% (typical at +22.5dBm output)  
- **Package:** 12-pin UCSP (Ultra Chip-Scale Package)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions & Features:**  
- **High-Efficiency PA:** Optimized for low-power wireless applications.  
- **Integrated Power Control:** Adjustable output power via an external resistor.  
- **Low Supply Voltage Operation:** Suitable for battery-powered devices.  
- **Internal Matching:** Reduces external component count.  
- **Shutdown Mode:** Reduces power consumption when not in use.  
- **Applications:** Wi-Fi (802.11b/g), Bluetooth, Zigbee, and other 2.4GHz ISM band systems.

Application Scenarios & Design Considerations

2.4GHz to 2.5GHz Linear Power Amplifier

Alternative Part Number

  • HMC482ST89 --: Wideband gain block amplifier in SOT-89 that covers a similar frequency range and can replace the MAX2242 in many RF gain-stage applications.
  • BGA7210 --: Silicon RF amplifier with comparable gain and bandwidth, suitable as a functional substitute where layout can be adapted.
  • SBA-5089 --: Cascadable InGaP HBT gain block offering similar gain and linearity, commonly used as an alternative to MAX2242-type amplifiers.
  • LMH6629MF --: High-speed voltage-feedback op amp with comparable bandwidth and supply range, suitable drop-in for many MAX2242EBC signal-chain applications.
  • AD8009ARZ --: Very high slew-rate current-feedback amplifier offering similar AC performance and supply flexibility as the original part.
  • OPA695IDBVR --: Wideband current-feedback op amp with low distortion and similar package/supply options, usable as a functional substitute.
