Description and Introduction

0.05-6 GHz, Cascadable Active Bias InGaP/GaAs HBT MMIC Amplifier Part SBB-5089Z is manufactured by RFMD (RF Micro Devices). Here are the specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Frequency Range:** 50 MHz to 4000 MHz  
- **Gain:** 14.5 dB (typical at 900 MHz)  
- **Noise Figure:** 1.4 dB (typical at 900 MHz)  
- **Output IP3 (OIP3):** 36 dBm (typical at 900 MHz)  
- **P1dB (Output Power at 1 dB Compression):** 21 dBm (typical)  
- **Supply Voltage (Vdd):** 5 V  
- **Current Consumption:** 85 mA (typical)  
- **Package:** SOT-89  

### **Description:**  
The SBB-5089Z is a high-linearity, low-noise amplifier (LNA) designed for applications requiring high dynamic range and low noise performance. It is suitable for cellular infrastructure, wireless communication, and other RF applications.  

### **Features:**  
- High linearity with excellent OIP3 performance  
- Low noise figure for improved receiver sensitivity  
- Wide operating frequency range (50 MHz to 4 GHz)  
- Single 5V supply operation  
- Internally matched for ease of integration  
- RoHS compliant  

This information is based solely on the available knowledge base for the SBB-5089Z from RFMD.

Application Scenarios & Design Considerations

0.05-6 GHz, Cascadable Active Bias InGaP/GaAs HBT MMIC Amplifier

Alternative Part Number

  • PGA-103+ --: Monolithic amplifier in the same gain class with similar frequency range; widely available and pin-compatible in many RFMD SBB-5089Z designs.
  • MAR-8ASM+ --: Low-cost cascadable MMIC amplifier covering DC to 1 GHz with comparable gain and output power; common drop-in substitute for SBB-series gain blocks.
  • ERA-5SM+ --: Wideband InGaP HBT gain block with similar gain and P1dB performance; a well-known alternative when the original RFMD part is unavailable.
  • GALI-39+ --: Monolithic Darlington gain block with comparable gain and frequency range, low cost and good linearity, suitable substitute for SBB-5089Z in many RF designs.
  • HMC311SC70 --: InGaP HBT gain block covering DC to 6 GHz with similar gain and output power, offering a higher-performance alternative when layout allows a different package.
