The ACT41000+ACT43750REF01 combines the functionality of the ACT41000 RF point of load (RFPoL) regulator and the ACT43750 RFPoL drain-switch driver / gate bias regulator to provide a complete GaN RFPA biasing solution including proper sequencing and autocalibration to optimize the performance.

The design performs proper bias sequencing to prevent damage, and the autocalibration feature adjusts the gate drive voltage to match the optimal IDQ of the specific RFPA. It is an optimum solution for radio frequency (RF) power amplifiers (PAs) that demand fast transient, high current pulsed loads with maximum efficiency.

This EVK ships as a standalone board that is specifically configured for the QPA2612 RFPA but can be reconfigured and used with many other GaN RFPA’s with voltages up to 24V and currents up to 4A. All data is taken with the QPA2612.
