Abstract
Embodiments are described for modules, multi-stage systems, and related methods for radio frequency (RF) power amplifiers with reduced size and weight requirements. Fluid cooling is incorporated directly into the power amplifier (PA) module design rather than requiring PA modules to be mounted on separate cooling devices. For one embodiment, a PA module includes a circuit board, RF circuit components, a ground plane, and a cooling plate having one or more cooling channels to receive a cooling fluid. The cooling channels are positioned to dissipate heat from the RF circuit components through the ground plane. For a further embodiment, the PA module also includes RF bias and power electronics within a housing for the PA module without requiring an external control board or power conversion electronics. Also disclosed are multi-stage PA systems having a plurality of PA modules that are similarly cooled using cooling channels.
