High-power amplifiers (HPA) typically require proper biasing from a power controller in RF front-end transmitters to meet front-end power efficiency requirements. This reference design combines a TI HPA biasing controller with a TI Gallium nitride (GaN) half-bridge power stage to demonstrate variable GaN HPA gate-biasing control along with GaN HPA gate or drain pulsing.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
