    摘要: Transistor devices are provided configured to operate at frequencies above a typical first cutoff frequency. In one aspect, a method is provided for configuring a transistor device to operate above a first cutoff frequency. The method comprises selecting a desired operating frequency range and a desired output power for a transistor associated with the transistor device, analyzing the effects of phase velocity mismatch on the overall gain of a plurality of different sized transistors, and evaluating the primary and secondary gain regions of the plurality of different sized transistors. The method further comprises selecting a transistor sized to provide the desired output power at or close to the desired operating frequency range based on the analysis of the phase velocity mismatch and the evaluation of the primary and secondary gain regions.

    摘要: A common source, bi-directional microwave amplifier is described. More particularly, the present invention is a microwave, common source, bi-directional amplifier that includes a first amplification path and a second amplification path wherein the signal directional flow is controlled through the selective biasing of the first amplification path and the second amplification path. Each amplification path is designed to optimize desired performance. For signal flow through the first amplification path, the first amplification path is biased-on and the second path is biased-off. For signal flow through the second amplification path, the second amplification path is biased-on and the first path is biased-off.
