Abstract
A power combiner for three active tno-terminal devices located under a common resonant cap is presented, An equivalent circuit with lumped e lements describing the coupling between the devices is derived from a numerical finite-element simulation of the resonator, The applied mono lithically integrated mounting technique for the active devices minimi zes parasitic elements and gains high reproducibility and symmetry. Ex perimental results with GaAs IMPATT diodes on diamond heatsink of up t o 500 mW at 91 GHz with a de to RF conversion efficiency of 9.0% and e xcellent combining efficiency demonstrate the capability for power gen eration in the mm-wave region.
