I’d normally recommend a linear regulator, LDO type typically used. A low noise LDO should be fine. Alternatively a SMPS DC/DC convertor is probably OK with adequate filtering and decoupling. It depends on your application requirements and how sensitive the system is to any AM and PM noise injected from the amplifier. Typically for power supply noise you want to be down in the microvolts range. Good RF PCB layout practice also important to prevent problems, like grounding and position of decoupling. Note that I’ve never personally had a customer report a power supply noise issue affecting a Qorvo gain block or LNA.
