ACT43750EVK3-101 Evaluation Kit
ACT437501EVK3-101 Evaluation Tool User Guide
The Evaluation Tool Users Guide describes the characteristics and operation of the Qorvo ACT43750EVK3-101 evaluation kit (EVK). It provides setup and operation instructions, schematic, layout, BOM, and test data.
To communicate with the EVK, a USB Dongle and a Graphical User Interface (GUI) is provided.
This EVK demonstrates the ACT43750-101 Radar Power IC.
QPA2811PCK01 Reference Design
The QPA2811PCK01 Reference Design provides the user with a QPA2811EVB mated to a Qorvo ACT43750 bias controller PCB.
The QPA2811 a high-power X-band GaN amplifier that covers 8.5 – 10.55 GHz. It provides 48.9 dBm of saturated output power and 27.9 dB of large-signal gain while achieving 48.5 % power-added efficiency. The QPA2811 requires a negative gate bias voltage rail, startup and shutdown sequencing, IDQ calibration, and drain switching circuitry.
The ACT43750 provides the requirements above, plus fault protection and built-in power management that allows the customer to test both boards from a single 24V input.
The Reference Design User Guide describes the characteristics and operation of the QPA2811PCK01 Reference Design. It provides setup and operation instructions, schematic, layout, BOM, and test data.
A Graphical User Interface (GUI) and USB Dongle are provided to communicate with the reference design via I2C from a laptop computer.
This reference design demonstrates both the QPA2811 and the ACT43750 operation.
