Abstract: A transistor comprises a semiconductor substrate and a barrier metal layer forming a Schottky barrier. One or more insulated gates may be positioned adjacent to an edge of the Schottky barrier. By applying a reverse bias voltage between the semiconductor substrate and the barrier metal, and applying a gate voltage between the one or more insulated gates and the barrier metal, a reverse bias current may be increased to a reverse bias conducting state. When the gate voltage is sufficient, the transistor may conduct current between the semiconductor substrate and the barrier metal. For example, voltages may be applied to an n-type substrate and an insulated gate (both relative to the barrier metal), and a current may flow from the semiconductor substrate to the barrier metal. The transistor may operate as a switch, a filter, a rectifier, an oscillator, or an amplifier.

Abstract: A novel digitally controlled antenna tuning circuit that enables the implementation of low cost, wideband tuning circuits for antennas in receive applications. The invention is operative to switch a plurality of tuning elements into and out of a main receive signal path. Each individual tuning element is switched into or out of the receive signal path using a single PIN diode. For series connected tuning elements, the diode is connected in parallel to the tuning element. For tuning elements connected in parallel, the diode is connected in series with the tuning element. The diodes are switched in accordance with control voltages which forward bias the diodes to effectively create a low resistance path thus either inserting or removing a tuning element from the receive signal path depending on its configuration in the circuit.

Abstract: A novel antenna system for receiving transmissions in the VHF and UHF frequency bands particularly suitable as a miniaturized antenna for UHF reception, such as of digital video broadcasting transmissions. The antenna system utilizes a combination of three techniques including (1) the use of dialect loading using a high dielectric constant ceramic substrate; (2) an antenna dielectrically loaded and tuned to a significantly higher frequency than desired; and (3) use of a tuning circuit to compensate for the frequency offset of the antenna thereby shifting the resonant frequency to cover the entire band. The antenna is intentionally designed to be too small to radiate at the frequency of interest. The antenna element is then ‘forced’ to be tuned to the desired lower frequency using passive (or active) reactive components as part of a tuning circuit. Multi-band operation is achieved by providing a bypass switch to connect the antenna element either to (1) a first receiver without the tuning circuit (i.e.
