Latest Patents

John R Anderson holds a patent for a "Multiple FET device having direct-coupled stages for improved microwave." This invention features a field effect transistor microwave circuit device that includes first and second field effect transistors with common source connections. A pair of coupled transmission lines connects the drain of the first transistor to the source of the second transistor, and the source of the first transistor to the gate of the second transistor. The cross-coupled transmission lines function as a balun between the transistors. The device is formed in III-V semiconductor and has an increased operating range in microwave frequencies. In alternative embodiments, the balun is connected to the circuit output, allowing for the cascading of multiple FET devices. The balun can be integrated into the device structure or connected as a discrete element in a hybrid circuit arrangement.
