Latest Patents
Kohno's latest patents include innovative designs for microwave amplifiers. One of his patents describes a microwave amplifier that features a field effect transistor with its source grounded. The drain of the transistor connects through a first inductor of gold wires to an output-side matching circuit, while the gate connects through a second inductor of gold wires to an input-side matching circuit. Additionally, a series circuit comprising a capacitor and a third inductor is positioned near the input-side matching circuit, enhancing performance.
Another notable patent outlines a microwave amplifier that includes an amplifier, an impedance matching circuit, and an open stub. The impedance matching circuit consists of input and output side distributed constant lines, each having a length equivalent to a 1/4 wavelength of the highest frequency signal in the desired frequency band. The open stub's length can be varied to adjust the narrow frequency band in which the amplifier achieves maximum gain, thereby reducing return loss and facilitating uniform tuning.
