Abstract :
The design and construction of a high power X-band quasi-optical power combining array is described. This array extends our previous work to two dimensions using a coupled network of GaAs power MESFET oscillators. Preliminary measurements suggest that a 6/spl times/6 array produces a total power in excess of 30 Watts, with an effective radiated power (ERP) of greater than 2 kW.<>
