QPD1009

Overview

The QPD1009 is a Gallium Nitride (GaN) High Electron Mobility Transistor (HEMT) designed for radio frequency power amplifier applications. It operates from DC to 4 GHz with a drain-source breakdown voltage of 50 V and a continuous drain current of 700 mA. The device delivers an output power of 17 W, achieving a power-added efficiency of 72% and a gain of 24 dB at a 28-50 V supply. Packaged in a QFN-16 surface-mount format, it supports a power dissipation of 17.5 W and functions within a temperature range of -40°C to +85°C.

Feature Summary

• High power-added efficiency for improved energy utilization in RF systems
• Wideband operation capability covering DC to 4 GHz frequencies
• Robust thermal performance supporting high power dissipation levels

Applications

• Base station power amplifiers
• Electronic warfare systems
• Military radar transmitters

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout compatibility and electrical tolerances. Ensure that the procurement channel provides traceable documentation confirming the component originates directly from Qorvo or an authorized distributor. Check for moisture sensitivity labeling prior to soldering to prevent package damage during reflow processes.

Selection Notes

Select this component when designing amplifiers requiring high linearity and efficiency in the sub-4 GHz spectrum. Evaluate the thermal management requirements carefully, as the 17.5 W power dissipation rating necessitates adequate heat sinking on the exposed pad. Confirm that the system bias voltage aligns with the 28-50 V operational window to ensure optimal performance and device longevity.

Part Context

The QPD1009 belongs to Qorvo's portfolio of GaN-on-SiC power transistors engineered for demanding RF environments. This series targets infrastructure and defense markets where reliability and wide bandwidth are critical. It complements other Qorvo active components by providing high-power gain stages suitable for integration into complex transmitter architectures.

Replacement Considerations

Consult the official Qorvo replacement guide for verified cross-reference part numbers. Do not substitute with generic GaN FETs without verifying matching S-parameters and thermal resistance characteristics.
