Abstract This paper proposes the use of an inverse class-E amplifier with a tunable parallel resonator at the output port in order to obtain a high power-added efficiency (PAE) and output power in a wide frequency range. The tunable resonator circuit has a constant Q factor in the operating frequency range, and since the circuit has a varactor diode, the inductor and capacitor values of the res...

We consider effects of a long-wavelength disorder potential on the zero conductance state (ZCS) of the microwave-irradiated 2D electron gas. Assuming a uniform Hall conductivity, we construct a Lyapunov functional and derive stability conditions on the domain structure of the photogenerated fields. We solve the resulting equations for a general one-dimensional and certain two-dimensional disord...
