He has made significant contributions to the field of electronics, particularly in the development of high-frequency modules for laser diodes. With a total of 3 patents to his name, Satou's work has had a considerable impact on the industry.

Latest Patents

One of Satou's latest patents is a high-frequency superposing module for driving a laser diode. This innovative module includes an oscillating circuit and an impedance matching circuit. The impedance matching circuit features a capacitor connected in series between the emitter of a transistor and the terminal through which a laser-diode drive signal is output. Additionally, a capacitor is connected in parallel between the drive-signal output terminal and the ground. The oscillating circuit incorporates an inductor serving as a choke coil connected between the drive-signal output terminal and the collector of the transistor, allowing the drive-signal output terminal to function as a power input terminal for the oscillating circuit.

Another significant patent is an oscillator designed for driving a laser diode. This oscillator includes a transistor, a first bias resistor connected between the base of the transistor and a power input terminal, and a second bias resistor connected between the base of the transistor and a control-voltage input terminal. When the control-voltage input terminal is grounded, the bias voltage at the base of the transistor falls below a predetermined threshold, causing the oscillator to stop oscillation. Conversely, when the control-voltage input terminal is open, the bias voltage at the base of the transistor exceeds the threshold, resulting in the oscillator starting oscillation.
