QPA9121TR7

RF Amplifiers Overview

The QPA9121TR7 is a GaAs driver amplifier from Qorvo, operating within the 2.3 GHz to 5.0 GHz frequency range. It delivers high gain of 28 dB with a noise figure of 5 dB. The device requires a 5 V supply and draws 95 mA of current. Key performance metrics include a P1dB compression point of 25.5 dBm and an OIP3 of 30 dBm. It is housed in a compact SMT-16 (3x3 mm) package and supports an operating temperature range from -40°C to +105°C.

RF Amplifiers Feature Summary

• Utilizes GaAs technology for robust RF performance
• Designed as a high-gain driver stage
• Operates on a single 5 V power supply

RF Amplifiers Applications

• Wireless infrastructure driver stages
• Point-to-point microwave radio systems
• Broadband communication equipment

RF Amplifiers Procurement Notes

Verify the specific suffix TR7 confirms the reel packaging format required for automated assembly processes. Ensure compatibility with standard SMD/SMT reflow profiles for the SMT-16 package. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated environments.

RF Amplifiers Selection Notes

Select this component when a high-gain driver stage is required across the 2.3–5.0 GHz spectrum. The 28 dB gain and 25.5 dBm P1dB make it suitable for intermediate amplification. Compare against the QPA9120 if lower noise figure is prioritized over output power, noting the QPA9120 uses Si technology.

RF Amplifiers Part Context

This part belongs to the QPA9121 series of RF amplifiers manufactured by Qorvo. It is distinct from the QPA9120, which offers wider bandwidth but different noise characteristics. The QPA9121EVB-01 serves as the dedicated evaluation board for testing this specific amplifier module.
