At the end of the HMC980 d.s., in the applications section, fig 2, two things:
-- Is the direction of the current wrong?
-- is the order of the amplifiers reversed?
Yes, you are right, it is common practice to have higher power AMP at the output stage.
However, the main intend of this block SCH is to show that multiple HMC980`s can be used in daisy chain configuration to bias multiple amplifiers, one HMC980 enabling the other for the protection of the amplifiers.
