Title: The Innovations of Tadahiko Maeda
Introduction
Tadahiko Maeda is a prominent inventor based in Menlo Park, CA (US). He has made significant contributions to the field of radio apparatus technology, holding a total of 11 patents. His work focuses on improving the efficiency and performance of radio communication systems.
Latest Patents
One of Maeda's latest patents involves a radio apparatus where the band of a loop filter of a synthesizer in a blank channel searching state is narrower than in a communicating state. This innovation allows for the measurement of the radio wave environment, enabling the determination of necessary characteristics for the radio apparatus based on the measured conditions. The power consumption is decreased while improving the efficiency of the output power. Additionally, the current consumption of a power amplifier is measured, and a matching circuit of the antenna is adjusted to reduce antenna loss. Maeda's design also includes a method for removing DC offset from transmitted power and reflected waves, which compensates for frequency characteristic deterioration in the receiving portion. Furthermore, a transmission power detecting portion is structured as an IC chip, which detects transmission power corresponding to leakage currents, thereby suppressing power loss and further decreasing power consumption.
