Qorvo QPA0813 8–11GHz 0.7W X-Band Driver Amplifier
Qorvo QPA0813 X-Band Driver Amplifier
The QPA0813 from Qorvo is a compact, high-performance X-band driver amplifier operating from 8 to 11GHz. Fabricated using Qorvo’s 0.15µm GaAs pHEMT process, it provides 28.5dBm saturated output power, 19dB small-signal gain and 50% power-added efficiency.
An integrated enable/disable function supports fast RF on/off control for pulsed radar applications. The RF input and output are internally matched to 50Ω, helping simplify integration into radar, point-to-point radio and VSAT communication systems.

Compact Driver for X-Band RF Systems
The QPA0813 combines useful output power, high efficiency and a small package footprint. Its 3 × 3mm QFN package is particularly suitable for compact RF front ends and phased-array architectures where limited PCB space and tight element spacing are important.
The device can operate as a driver stage before a higher-power X-band amplifier or as a moderate-power amplifier in compact communication and radar transmit chains.
Enable/Disable Control
The built-in enable/disable function provides fast RF switching for pulsed operating modes. This feature makes the QPA0813 suitable for radar transmit chains requiring rapid control between active and inactive states.
For linear communication applications, the amplifier provides 19dB small-signal gain with internally matched RF ports, reducing the need for extensive external matching components.
Typical Applications
The QPA0813 is suitable for:
X-band radar systems
Phased-array radar
Radar driver stages
Point-to-point microwave communication
VSAT communication systems
Defense and aerospace RF equipment
Pulsed RF transmitters
X-band test and measurement equipment
Qorvo identifies radar, point-to-point communications and VSAT communications as the principal applications for the device.
