Title: Norihiro Shimada: Innovator in High-Frequency Technology

Introduction

Norihiro Shimada is a prominent inventor based in Shiga-ken, Japan. He has made significant contributions to the field of high-frequency technology, holding three patents that showcase his innovative spirit and technical expertise.

Latest Patents

Shimada's latest patents include a receiving module and a TDMA-system receiver designed to broaden the bands of received signals and lower the frequencies of intermediate frequency signals. These apparatuses are compact and contribute to cost reduction. The receiving module consists of a low-noise amplifier, a high-frequency LC filter, a Gilbert-cell type mixer, and baluns. The signal received by an antenna is amplified by the low-noise amplifier and passed through the LC filter. Subsequently, the signal is mixed with a local oscillation signal by the Gilbert-cell type mixer to convert it into an intermediate frequency signal. Another notable patent is a high-frequency composite component that achieves a reduction in size and weight while providing high performance. This component is incorporated into a portable wireless device, which includes a multi-layer substrate, a low-noise amplifier (LNA), and a band-pass filter (BPF) as parts of a high-frequency circuit.
