QPA4463ATR7

Video Amps And Modules Overview

The QPA4463ATR7 is a high-performance SiGe HBT MMIC amplifier from the QPA4463A series, manufactured by Qorvo. It operates across a frequency range of DC to 3500 MHz and utilizes a Darlington configuration for high FT and thermal stability. The device features an internally matched 50-ohm input and output, housed in a lead-free, RoHS-compliant SOT-363 package. Key electrical specifications include a typical gain of 16.3 dB at 1950 MHz, an output IP3 of +29.5 dBm, and a noise figure of 2.8 dB at the same frequency. It requires a single positive voltage supply with a bias resistor.

Video Amps And Modules Feature Summary

• Utilizes a Darlington configuration to provide high transition frequency and excellent thermal performance while minimizing leakage current between junctions.
• Features cancellation of emitter junction non-linearities to achieve higher suppression of intermodulation products.
• Internally matched to 50 ohms, requiring only two DC-blocking capacitors, bypass capacitors, and an optional RF choke for operation.
• Offers robust ESD protection with a Class 1C Human Body Model rating.

Video Amps And Modules Applications

• Cellular, PCS, GSM, UMTS systems
• Power Amplifier (PA) Driver Amplifier
• IF/RF Buffer Amplifier
• Wireless Data and Satellite communications

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix 'ATR7' corresponds to the 3000-piece reel quantity as defined in the manufacturer's ordering information. Confirm that the component meets RoHS compliance standards and is lead-free. Ensure handling precautions are followed due to the device being ESD-sensitive, specifically adhering to the Class 1C HBM rating guidelines during assembly and testing.

Video Amps And Modules Selection Notes

Select this component for applications requiring wideband amplification from DC to 3500 MHz with high linearity. The internal 50-ohm matching simplifies circuit design by reducing external component count. Consider the single positive voltage supply requirement and the need for an external bias resistor when designing the power delivery network. Evaluate the thermal resistance characteristics if operating near maximum temperature limits.

Video Amps And Modules Part Context

The QPA4463ATR7 belongs to the QPA4463A family of SiGe HBT MMIC amplifiers. This series is designed for general-purpose wireless applications, offering a balance of gain, linearity, and noise performance. The ATR7 suffix indicates a specific tape-and-reel packaging format intended for automated surface-mount assembly processes.

Video Amps And Modules Replacement Considerations

QPA4463ASQ and QPA4463ASR are alternative packaging options for the same QPA4463A die. No direct functional substitutes are listed in the provided documentation; verify compatibility with existing board layouts and biasing requirements before considering other models.
