Toward standard figures-of-merit for spatial and quasi-optical power-combined arrays

A consistent set of figures-of-merit is proposed for the standard characterization of spatial and quasioptical power-combined arrays. A new figure-of-merit, the effective transmitter power, is presented along with slightly modified definitions of standard figures-of-merit. The definitions of these figures-of-merit have been chosen to more directly compare the performance of spatial and quasioptical power-combined arrays with one another and with conventional circuit power-combined transmitters and amplifiers
