Title: Toshiki Matsui: Innovator in Radio-Frequency Technology

Introduction

Toshiki Matsui is a prominent inventor based in Nagaokakyo, Japan. He has made significant contributions to the field of radio-frequency technology, holding 3 patents that showcase his innovative spirit and technical expertise.

Latest Patents

Matsui's latest patents include a radio-frequency module and a communication device. The radio-frequency module features a power amplifier, a first bias circuit, and a second bias circuit. The first bias circuit incorporates a register that receives a first digital control signal corresponding to the power mode of the power amplifier, along with a current generation circuit that produces a first bias current. Similarly, the second bias circuit includes another register that receives a second digital control signal and a current generation circuit that generates a second bias current based on the information in the register.

Another notable patent is the tracker module, which consists of a module laminate and an integrated circuit, along with a filter circuit and an output terminal. The integrated circuit features at least one switch of a switched-capacitor circuit and at least one switch of a supply modulator. The switched-capacitor circuit is designed to generate multiple discrete voltages, while the supply modulator creates an intermediate output by selectively switching among these voltages based on an envelope signal. This envelope signal is associated with an external circuit that the tracker module processes. The filter circuit then filters the intermediate output to produce a filtered output, which is provided to the external circuit through the output terminal.
