Description and Introduction

DC-5000 MHz, Cascadable SiGe HBT MMIC Amplifier The part **SGA-5289Z** is manufactured by **RFMD** (RF Micro Devices).  

### **Specifications:**  
- **Type:** RF Amplifier  
- **Frequency Range:** 50 MHz to 4000 MHz  
- **Gain:** 20 dB (typical)  
- **Noise Figure:** 2.5 dB (typical)  
- **Output Power (P1dB):** 23 dBm (typical)  
- **Supply Voltage:** 5V  
- **Current Consumption:** 80 mA (typical)  
- **Package:** SOT-89  

### **Descriptions and Features:**  
- **Wideband Performance:** Operates from 50 MHz to 4 GHz, making it suitable for various RF applications.  
- **High Gain:** Provides a typical gain of 20 dB, enhancing signal strength.  
- **Low Noise Figure:** Ensures minimal signal degradation with a typical noise figure of 2.5 dB.  
- **High Linearity:** Supports high output power with a P1dB of 23 dBm.  
- **Single Supply Operation:** Requires only a 5V supply, simplifying design integration.  
- **Compact Package:** Housed in an SOT-89 package for space-constrained applications.  

This amplifier is commonly used in wireless infrastructure, broadband communication, and other RF systems requiring high gain and low noise.
