QPL9057TR7

RF Amplifiers Overview

The QPL9057TR7 is a flat-gain, high-linearity, ultra-low noise amplifier manufactured by Qorvo. It operates within a frequency range of 600 MHz to 4.2 GHz and utilizes GaAs technology in an 8-DFN (2x2 mm) surface-mount package. Key electrical parameters include a gain of 22.8 dB, a noise figure of 0.54 dB, a P1dB compression point of 17 dBm, and an OIP3 of 32 dBm. The device requires a 5 V supply with a current consumption of 50 mA and functions reliably between -40°C and +105°C.

RF Amplifiers Procurement Notes

Verify the specific suffix TR7 indicates reel packaging when ordering. Confirm the operating voltage and temperature ranges match your system requirements. Ensure ESD protection protocols are followed during handling due to the small DFN-8 package. Cross-reference the datasheet for pinout compatibility if replacing existing designs. Validate that the GaAs technology aligns with your manufacturing capabilities.

RF Amplifiers Selection Notes

Select this component for applications requiring low noise figures and high linearity in the 600 MHz to 4.2 GHz range. Consider the 22.8 dB gain and 0.54 dB noise figure for sensitive RF front-ends. Evaluate the 5 V supply requirement against your power budget. The compact 2x2 mm package is suitable for space-constrained designs. Compare OIP3 and P1dB values against system dynamic range needs.
