Abstract: This work is to present a versatile K-band waveguide resonator bandpass filter structure capable of producing various responses with a pair ... tuned to produce, for example, three symmetric ...

For diode operation of the device, the gate electrode and one of the ohmic electrodes of a normally off AlGaN/GaN HEMT were short-circuited, which was called as a gated-anode diode (GAD). The ...
