An ultra-high power amplifier and switch arrays on single wafer

A novel X-band single wafer amplifier and switch arrays are designed to work in a high Q circular waveguide cavity. This design can significantly reduce power leakage at the plane where the wafer is inserted, which is essential to achieve high Q and ultrahigh power. The array is achieved in an overmoded circular waveguide. The mode being exited and/or controlled by the array is the TE/sub 01/ mode. We hope that the use of an overmoded waveguide and the TE/sub 01/ mode would allow us to extend the power handling capabilities of the device by orders of magnitude beyond the state-of-the-art for semiconductor devices. We present the general design of the array and show several implementations.
