QPA2735TR7

RF Amplifiers Overview

The QPA2735TR7 is a packaged low noise amplifier (LNA) designed for the 13 to 20 GHz frequency range. Fabricated using Qorvo's 90nm pHEMT process, this device provides high performance in a compact 16-QFN (4x4 mm) package. Key electrical specifications include a small signal gain of 25.5 dB and a typical noise figure of 1.3 dB. The amplifier delivers an output power at 1dB compression (P1dB) of 18 dBm. It also exhibits third-order intermodulation distortion (IMD3) levels of -60 dBc when operating at an output power of 0 dBm per tone.

RF Amplifiers Feature Summary

• High linearity with -60 dBc IMD3 at 0 dBm output
• Low noise figure of 1.3 dB for sensitive reception
• Compact 16-QFN surface-mount packaging
• Optimized for Ka-band satellite communications

RF Amplifiers Applications

• Ka-band satellite communication terminals
• Point-to-point microwave radio links
• Military electronic warfare systems
• Test and measurement instrumentation

RF Amplifiers Procurement Notes

Verify the specific revision suffix against the manufacturer's current datasheet to ensure compatibility with design requirements. Confirm that the 16-QFN footprint matches the PCB layout exactly. Check for any recent product change notices regarding pinout or thermal characteristics before finalizing procurement orders.

RF Amplifiers Selection Notes

Select this component when a balance of high gain and low noise is required in the 13-20 GHz band. The 18 dBm P1dB rating supports moderate output power needs without external amplification. Ensure the application can accommodate the specific bias voltage and current requirements defined in the official electrical characteristics table.

RF Amplifiers Part Context

This part belongs to Qorvo's QPA series of RF amplifiers, which are built on proprietary pHEMT technology. The TR7 suffix indicates the tape and reel packaging format intended for automated surface-mount assembly. It serves as a packaged solution compared to the bare die variant, offering integrated thermal and electrical connections.

RF Amplifiers Replacement Considerations

Direct substitutes may include other Qorvo LNAs in the same frequency range with similar gain and noise specifications. Verify that alternative packages match the thermal and pin-out requirements of the existing design. Cross-reference with the manufacturer's replacement guide for qualified equivalents.
