High-power Reconfigurable Microwave and Millimeter-wave Devices
While a variety of technologies have been developed for reconfiguring RF receivers (e.g. solid-state electronics, MEMS, and ferroelectrics), few options exist for high-power tunable transmitters. This is particularly the case for high-frequency systems at K-band and beyond. This talk will review challenges related to developing high-power reconfigurable devices and recent solutions based on 3D high-Q components. Tuning technologies with piezoelectric actuators and resonant plasma cells will be discussed for power levels up to 100 W and applications up to 100 GHz. Linearity, failure modes and lifetime considerations will be discussed as well.
