I have a problem where I would like to have 2 options for powering my board - via multiple LDOs or via a benchtop DC power supply with one output.
The issue is that there are four HPAs each consuming 6V @ 1000mA so they each have their own LDO. I would also like to be able to power them from one of the outputs of a benchtop DC power supply for testing.
Does anyone know how I would go about placing a connector so that the HPAs can pull from either individual power supplies or all from the same power supply?
Note: This is a pretty space-constrained (~2"x3") RF board.
