Description
This document describes the characteristics and operation of the Qorvo ACT43750EVK3 evaluation kit (EVK). It provides setup and operation instructions, schematic, layout, BOM, GUI, and test data. This EVK ships as a standalone board that can be evaluated independently or with a GaN RF Power Amplifier.The ACT43750 is an integrated power solution that controls GaN RF PA drain and gate:• Generates negative gate voltage for the PA gate• Properly sequenced turn on and turn off• Automatic gate voltage / drain current calibration• Drain voltage switchingIt is an ideal solution for radio frequency (RF) power amplifiers (PAs) that demand fast transient, high current pulsed loads.
Features
Qorvo recommends that the user evaluate the EVK functionality with an RF PA and with the EVK connected to a PC runningthe graphical user interface (GUI) software. The GUI allows the user to enable/disable the outputs and to customize theexact voltage and current requirements for the specific RF PA being tested. The user can use the ACT43750 GUI to set theRF PA Idq bias current target, and the EVK autonomously finds and stores the optimal gate voltage for the Idq bias current.
Typical applications
- RF GaN / GaAs PA Power Supply
- Military Radar System
- Civilian Radar System
