Title: **Innovator Syuuji Matsuura: Pioneering Advances in Cable Modem Technology**
Introduction
Syuuji Matsuura, an accomplished inventor based in Ikoma, Japan, has amassed an impressive portfolio of 20 patents throughout his career. His innovative contributions focus primarily on advancements in cable modem tuner technologies, demonstrating his commitment to enhancing communication systems.
Latest Patents
Among Matsuura's latest inventions is a highly sophisticated cable modem tuner. This invention features an intermediate frequency (IF) input signal corresponding to a selected reception channel, which passes through a surface acoustic wave (SAW) filter to an IF automatic gain control (AGC) circuit. Here, the signal's amplitude is adjusted to a predefined level before it is sent to a down converter unit. This unit selectively outputs either a Low-IF signal, achieved by down-converting the IF input signal, or a High-IF signal, which is amplified without frequency conversion, depending on external instructions. The associated filter circuit can be configured to allow only the Low-IF signal to pass or to accommodate both Low-IF and High-IF signals.
Another noteworthy patent revolves around converting the output of an IF amplifying circuit included in a tuner. This patented technology optimizes the signal for transmission by using a SAW filter to eliminate unnecessary signals. Following this filtration, the resulting signal has a consistent gain ensured by an IF AGC circuit, amplified by an IF amplifying circuit, and cleaned of unwanted band components via a low-pass filter. The balanced IF signals are then provided to a quadrature amplitude modulation (QAM) demodulating circuit through an unbalance/balance converting circuit.
